Factoring Sums and Differences of Cubes 

Why are all the good math teachers on RU-vid and not in the class....grr.

I'm a sophomore in high school thank you for the tutorial. My math teacher literally gave us a packet and didn't teach us this.

funny how you teach better in 5 minutes what takes my teacher takes 55 minutes to do

Every math period i wont listen to my teacher and just watch it on youtube. Its more understandable 😂

To remember the formula (+&-) I use SOAP Same sign, Opposite sign, & Always Positive.

come back and watch any time :)

Literally 11 years later and your video is still helping people. THANK YOU SO MUCH!!

Lol Ty, I remember watching you back in high school and now I'm watching you again now that I'm in college to refresh my memory. Thank you for making these!

Thank you so much! You explain things 1000 x better than my teacher xD

i know this video is super old but with the distance learning thing going on rn because of covid-19 this was super super helpful. thank you!

I was on the internet for hours trying to find a video that would explain this properly... THANK YOU SO MUCH!!

This guy is the most helpful resource to me outside of person to person tutoring.

Keeping the formulas handy and using them sure beats staring at it for a half hour and pulling your hair out. Thanks!

You truly are a great teacher. Very helpful and clear modeling the procedures. You’ve been a life saver when trying to help my daughter with her homework. Thank you!

I like your explanation more than Khan Academy's

Thank you very much! I was struggling with this concept in my Honors Advanced Algebra class, but it helped me get a bit more back on track. :)

you have helped me so so much. I live in florida and the teachers dont teach you really anything. im not good at math at all and you explaning this to me has helped like so much. thank you so much! i wish i would have found you a long time ago.

id just lijke to say thank you bc youre the only reason ive survived 7th grade and now youre guiding me through 8th grade thanks bro

Very helpful !!! I was struggling until I watched this video. Please keep making them! :)

Thank you for existing... my math teacher just gave us a packet and expected us to remember what we did in math 6 months ago 😧. Great refesher!

Thanks Patrick! I am taking an online algebra course, in which we have two different video instructors. One guy is AWESOME, but the lady that does a minority of the other power point videos couldn't explain her way out of a paper bag if her life depended on it. You pretty much helped me save my quiz score ahead of taking the quiz. Your video explains this concept far better than the woman who did our power point could have ever done! I wish we had video lessons like this 20-30 years ago when I was flunking math in high school. I now get A's- proof we get finer with age:-)

This is still relevant 13 years later thank youuu 😢

you have become my saving grace and i love you.

You. Are. A. Math. God! Thank you so much, I'm completely dumb when it comes to math yet you put this in such a direct and easy way and I now understand this. Liking and subscribing :)

@nm2941 you can rewrite 8x^3 as (2x)^3 and 64y^6 as (4y^2)^3 so that you have: (2x)^3 - (4y^2)^3 and then you just use the formula.

Thanks mister, you deserve a smile on our faces.

Thanks a lot man. I had to learn this on the last day before my test because my teacher didn't go through all the steps so it was so much more complicated.

So helpful! I've been struggling with the way my instructor threw so many formulas at me at once and flew through them. You broke it down and made it incredibly simple. I feel much more confident using them now. Thank you! (also your perfect square factoring formula video!) definitely subscribing!!

Finally, I understand. Usually this all looks like heiroglyphics to me.

I am doing my class online so I dont have the in class help but this explained just what I needed thank you :) you put it in a better way for me to understand it.

He's better then my teacher thanks man I learn more from you then my actual teachers

thanks helped so much, i couldn't understand it by just reading my notes, but this helped me understand it after the first time watching it ! thanks !

You're like the guardian angel of my math grade.

Every math video has hundreds of comments stating how much better the video is than the teacher... *My teacher just sends us to RU-vid*

I'm doing online school and I literally just got taught this 15 minutes ago and I didn't get it but you explain it so much better thank you!!👍

I wish you were our math teacher... Our teacher is really fast when teaching us stuff she keeps on jumping from one topic to another.

Thanks! I've been out sick for 3 weeks and hadn't a clueeee what was going on with this. Really helped:)

Life Saver! Learning a lot from you. Making math easier.

@Rhysabdeen happy that i can help you out : ) spread the word about the videos!!

Dude, totally saved me day before finals, thx a bunch:)

Omg this helped so much studying for my sophomore math quiz, thank you so much!

Great video. Still helping students 12 years later :)

i think the reason why we understand lessons in youtube more is because its not in a crowded space, we listen to it better and can see better

Thanks bro, you teach way better than my teacher!

You legit explained something that took my teacher an hour to do. YOU REALLY GON SAVE MY ASS

Thanks for this video. Extremely helpful. I wasn't understanding the material my teacher taught but after watching this video, I do now!

Your videos are such an awesome help. Thank you so much!

just wanted to say you are a life saver. my teacher is... well really bad at teaching, so I almost always need to watch your videos. What ever I don't understand from my teacher I pretty much get right away from you. You should really consider becoming a teacher.

Thank you, thank you, thank, thank, thank you SOOO much!!! Needed this for before my exam

Your video's are really saving me so much stress this semester! Thank you!!

never knew this formula until today..thanks!!!

Thanks for the help to society. You are a legend

Your AWESOME! You have saved me from my college Math class!!!

You're better than my Math teacher.

I missed this in class thanks for helping! BTW, I find this guy + Khan to be a good team in helping me with math- they both have their strengths :).

Using this to help me do limits in AP Calc. Really helped thanxx

Thanks man! I've been following your videos for a month now and I bumped my math grade from a 77% to a 96% (Honors)! :D :D :D

Thank you soooo much!!!! I skipped algebra I because i took it before highschool and i never learned this so i never knew how to do it!!!! Finals are coming up and i thought it would be a good time to finally look up how to do this!! haha

Thanks so much! I missed last class and didn't have time to do an example with my teacher.

i hope you're getting paid some good money for these videos, you're legit saving my life in math. thank you!

Very helpful, better than my college algebra teacher

this really helped i have an f in algebra 2 but this might help me pass my midterm thanks

I am taking a differential equations course in college and had to search this up. Thank you, patrickJMT.

I'm actually reviewing for my first periodical examination in Math. I'm taking a special exam since I was absent during the examination days. I had a lot of things assigned on me, and I'm really screwed up. I have three exams per day in three days, while I have projects, portfolios, and other tasks to do. I have such a limited time in reviewing for my special exams, but you really helped me a lot. There are a lot of topics that are included on the pointers to review, and you just solved one there. Thanks a lot!

great video, thanks a lot, really helped me when I missed a class at school like 2 days ago because I woke up late :(

no intro straight to the point i like it

Your writing is pretty neat for a left hand. Btw great video. Now I can understand so much better.

Helps so much more than my teacher thank you

You deserve a medal sir.

Our teacher in math is very cranky .. but I really love this lesson so I will learning because I can watch this video of yours .. .

The way you explained it helped out so much. I seriously do not learn well in-class as I do comfortably at home. Your way made it much easier for me. It'll be hard to remember for the test but at least I can finish my homework. Thank you!

Yo im a senior and im dumb as far as math goes so this helps. Thanks man.

Thank you very much. Much better explanation than the packet.

Thank you so much, I missed school and I had to learn this. You helped way more than friends, thanks.

Thank you! I missed the first half of my class the other day when they were doing this and you know the book is almost never any help. You made this much easier to comprehend, just hope I got it right!

Thank you for making something so much simpler to understand!

Best math youtuber of all time.

Thanks a lot bro. I need this to my subject calculus

Thank you!!! My made learning this so much easier and now I get it!

Im in AP calc and this refreshed my memory. Now I can find limits without getting stuck LOL

You are the math master thank you so much !!!! Love you this help a lot

thank you vey much this one helps me alot because of online class and our teacher sometimes is lagging so look up in youtube thanks again

Thank you sooo much... you just saved my life....

Thank you Patrick! I never understood factoring in high school, and I need it heavily in calculus 1. You made math that much more pleasant to work with. Thank you again.

Im doing online schooling since the whole covid-19 thing and this weeks assignment is sum and difference of cubes. I tried following my teachers notes but ehh i just ended up confusing myself even more. This video really helped me a lot thank you!

I think the answer of this sum of cubes is : (3y - 2)(9y^2 - 6y + 4) because according to the formula you are multiplying 3y by -2 but thanks it is really helpful.

thanks teacher for your best explanations maths .

You made it sound so easy thank you

Dude you literally saved my LIFE lmao 😭

i have to watch this to learn because online classes suck, thanks alot!

THANK YOU SO MUCH THIS HELPS ME UNDERSTAND BETTER!!!

You are the way i'm going to pass Advanced functions, thank you! :P

I love the way you presented, it was very clear. However, wouldn't it be easier for students (if you are a teacher) just to remember: First, write it without the cube. Opposite sign. Product of the two. Add the square. (To a sortof beat) I think that would be easier than memorizing the two formulas.

THANK YOU SO SO MUCH! I have a huge test coming up, and your video helped me understand these concepts so easily! You are an awesome teacher!

Thank you so much for this! I find it really fun after I know what I'm doing. :)

thanks for your help you are a genius in math God bless you always

Thank you! This helped a whole lot. You just saved my math grade!!!

i feel so stupid!! i have the hardest math teacher, and he makes us remember all equations by heart, and he never taught us this and just slipped 5 questions about this on the test, and i didn't realize how easy it was if i had known to just remember the equations :-(

you teach better than my elementary teacher and my high school teacher combined.

You know he's good at math when he does all his work in Sharpie.. Bold, my friend.. Bold..
