Rational Expressions: Adding and Subtracting. Ex 1 

Gosh, I really hate Math! Even if I listen as much as I can, I don't still get it.

....... Thank you so so so much for making a series on Rational expressions. I have a test on this tomorrow and since I missed out a day, I didn't understand anything but watching your videos really made me understand how to solve each and every problem that I get. Because of you, I don't have to worry about failing the test tomorrow.

Why cant teacher's teach like this??

I have a test next period and this video made me fell mire confident

my teacher took 2 hours to explain it and i still didnt get it a 3 min vid helped more than ever thank u man

You teach me more in 3 minutes than my math teacher does in an hour.

Thank you for explaining the factoring aspect of this problem. You simplified it in a way I can understand. A thousand thank you's!

One great thing about mathematics is that videos explaining how to work equations out, for the most part don't become outdated. Thank you for posting this some 9 years ago :-)

Finally. Ive been stuck on this for ages. Nice.

My teacher doesn't do it like you; you're better

I'm still lost

God bless you for doing this! You have no idea how helpful your videos are. Don't ever stop :)

Quiz tomorow and i had no idea how to do any of the material. Thank you so much.

Out of all the videos I watched on this topic he was the most clearest and helpful 🙌🏾

OMG this is really helpful. You're so much better than my math teacher. All my teacher does is brag and tease

Thank you so much this helped raise my mark on my math exam from all your vids

Thank you so much, because of you, i got an A on my test today.

Now thats what i call a math teacher ! Well my teacher is great too but i think im not paying attention in class! Thanks i learned a lot!! Got to pass my exam today!

You have no idea how grateful I am for this video. I found myself taking notes on paper. THANKS! :)

This is the first time I’ve understood it thank you

You could simplify 3x-17 over x^2-64 which would be 3x-17 over (x+8)(x-8)

Thank you so much!

Thank you so much for this video. I was literally pulling out my hair for a problem similar to this one.

My parents are most likely wondering why I'm silently screaming in victorious mood defining tones.... I'll tell them later. Right now, I'M GONNA PASS ALGEBRA!!! Thank you, patrickJMT!!

God bless you. You made me really understand this. Thank You SO! Much.

Why is this clearer to me than my actual math teacher

Thanks you saved my guts! (And that people is how you get a a quick, step by step explanation on an assignment on a topic which is completely new to you and score high on it without bothering to attend the actual class!!! XD )

Sweet, much thanks. Overthought this.

thanks for this . got a test today..wish me luck

glad i could help :)

This video was very helpful. thank you

Oh gosh! You just made it so much easier for me lol thank you this was very helpful!

this helped a lot, thanks.

i love you so much you make this so much easier

All you do is factor and then cancel out the x+8 because it is common and replace the cross by 1 which means multiply by one

i just notice ur using my fave marker "Sharpie" oemge thnx for the video..our teacher incourages us to watch video like this to understand the lesson more..aish

I still don't get it.

Thanks u really saved me

THANK YOU SO MUCH SIR

You saved my life! Thanks!

nice lesson..keep on creating more...thumbs up!!!

after watching this video a couple of times i finally understood what to do.... i did take me a while tho

but since the denominator at the end is a difference of squares wouldn't you simplify

i don't quite get that joke.

why does in your previous video of addition and subtraction of rational expressions, you didn't multiply the denominator of 5x^2 + 2x which is (x+2)(x-6)?

dude thank you so much

I have been getting D in algebra because i couldn't do my HW because i just had no idea what to do. My teacher is a nice lady but cant really teach me. Thank you so much for creating this channel. New subscriber. P.S. I have the problem 5/3n-2/2n m not sure what to do. Plase help :)

created at meh bday!!!....+it really hlped!!! tnx

thanks a bunch easily explained!

I think you add (x+9) to the top and bottom of the first fraction.

ya da real mvp

Funny how nice people around the world make short videos and post them online on how to do math for example, and they're wayyy better teachers than some of ours. they teach it faster and they don't get paid for it. If i had to name the problem, id say seniority. Some of my teachers at my school have been there for awhile so even if they're getting poor results they don't get fired and younger teachers who are more connected to us don't get hired.

what if you have a whole number on one side of it

Why did he change the denominator: (X+8) (X-8) back into x^-64? Please reply! Have a test Tuesday.

i actually got it already. thought it was hard

You can just leave the denominator x-8 x+8

I atleast understand the last parts thank you

this helped a lot tanks

that's what I was wondering...I think it should be if anything, a better answer.

Thank you!

thanks a million

THANK YOU!

What if there's no x^2, do i do the same thing?

What if my fractions both numerator and denominator are both not factorable

arnt you supposed to factor out x2-64 to (x+8)(x-8)

Thanks

So I need to use distributive property?

My teacher on math dindt teach like this he teach on a longer way so i dindt get it thanks for your video

Thanks!

thanks that help alot ,

We will have our 11th quiz and if I can't pass the test my parents will be called now pls tell me why did you change (x+8)(x-8) x2 - 64?

I don't know why but my answer is 10 --- x-8

Why the hell did u add the denominator?????

My brain cannot compute.

thank you

kind of frustrated...what if one denominator is just 3 and the other is say, x+9....how do you get two same denominators??? thanks

How tf did xSquared - 64 turn into x+8 and x-8? Sorry i'm just...really thickheaded to get it

Lol it’s funny that you gave the expressions a gender,but yea this video helped

This guy is left handed

when i search for math videos i write the title and this with it (patrickJMT)

Thank you so much.. :)

EXACTLY!

can you please use these formulas in word problems etc engineering,,manpower labor hours?

IS THERE A QUICKEST WAYYYY!??? SHORTCUTSSS!!!???

hey! thanks a lot dude. you're soo cooool.! :D

useful!

why did he subtract the 7 to 24?

how do you do that?

How do you bend the sharpie like that at 1:20?

U saved me

It helps

any tipson passing alg 1

What? 47 seconds into this vid and I’m still like wtf? I don’t get how you factorized (x) to the power of 2 minus 64 to - (x -8) & (x+8)?

OMG YOU'RE A LEFTIE! ME TOO!!! I thought I was the only one!!

why did he put it back to x^2 - 64 though it should be simplified? i'm confused :( should we really put it back or not? :(( but i get it how the process is. :) thanks

Where is subtraction

tnx

thanks.. veryhelpful :)

You are thee man

i still dont get it
