Solving Advanced Absolute Value Equations 

Finally I have understood double absolute value equations from your explanation. Only understanding it today after 2 years of serious struggle. Thank you so much sir. May the Lord remember you.

Really Helpful! I was trying to figure out how to solve absolute value equations with two absolute value operations and a loose number and I found this gem. Thank you!

How is someone this smart to know these things they don't teach in class? THANK YOU. Such a great video. never thought a 40 minute math video could pas by so fast

Omg thank you for your existence!!! Our great maths teacher was given a transfer and we now have a terrible temporary maths teacher who literally didn't do a single question on this and expects us to just know it. So thank you for saving my exam ❤️

Dude this helped so much. You deserve WAY more subscribers. Thanks for the help!

Thank you so much! I forgot a lot during quarantine and this not only helped me remember it also taught me more

after 2 days I finally get it.Tnxxxx

Omg! I was always terrified by absolute values problems this teacher made me realized that there is nothing to it. I understood the concept and I feel like I can solve any absolute value problem thrown at me. THANK YOU so much you are such a gifted teacher. I wish you could be my math teacher.

The video was tremendously helpful! Thank you very much GreeneMath!

really really helpful.I'm feeling that you are here to show us the brightest way.May you live long! From Ethiopia

Seeing sign charts in other than rational inequalities makes me happy :)))

I had never seen these approaches before. I have found that making graphs removes a lot of the mystery. they tell very quickly the number of solutions I should expect.

What a good video. I like your step-by-step and simplistic approach.

Thanks for the great explanation, helped me clear a lot of confusion I had about absolute value equations

Would you please let me know why you didn't include 1/3 and 1 - the critical points- at 11:20 and you wrote (1/3, 1) instead of [1/3, 1) for the middle section and for the last one [1, infinity)?

thank you for the explanation sir, very helpful.

very detailed, explained well and very helpful, thank you!

Ty man saved my grade keep puttin in the work

Great video! Helped a lot!

thank you, you are really good at explaining

Best video on all of RU-vid.

Thank you so much, it was really helpful for me!!

Great work, very interesting; thanks for sharing.

Here is where l understood double or triple or more absolute value equations clear-crystal

great help. thank you!

Really helpful . Like it

Hi! the video was really helpful, thanks a lot for the tutorial...I just had one doubt in the questions with double mods, if the value of x in any interval coincides with one of the bounds of it do we consider it or not? For eg. at 14:48, in case the value of x comes 1/3 itself, would we include it in our solns??

Thank you that's was very clear and easy to me to understand.

It was really helpful new subscriber from Algeria

Thanks for the explanation

this is really good! tysm!!

Thank you so much I truly appreciate you

So these 22:27 or 11:09 you put negative infinity and smallest number on interval on left? And middle stays the same? and the right part includes the largest number and positive infinity interval?

Really helpful!

Very well explained

Thank u very much it helps me to final exam

1) 12:00 so for that left side we are putting negative sign outside because we know what value makes the number negative inside the interval so we are using negative sign outside to make it positive - - = +? 2) What are we doing on middle part 13:00? are we trying to find intervals that make the expression 0? Ok for (3x - 1) we know 1/3 makes it 0 so any other value GREATER is going to be positive. But for (x-1) we know 1 makes it 0 but any value LESS than 1 is negative but why can we not say any value greater than 1 will result in positive like (3x-1)? Why we say GREATER value for that and LESS value for (x - 1) My random guess: (I am guessing the left side of line we focused on value that makes the expression negative which was 1/3 so we now went left to right so we said positive but for right side we are focusing on value that is greater than 1 to keep it positive for 1/3 or 1 so now we going right to left or negative?) 3) Are we picking left intervals that have less value than the other one like in 12:00 and 22:17? and right side we pick bigger interval number like 1/3 is less than 1 so we put 1/3 on left and 1 on right? Thanks Teacher Green

May someone please share the link to the previous lessons video on this section

Is it the same process when dealing with absolute value inequalitys? And do you have a video specific for that, let me know

37:52 I can change any quadratic absolute value equation to "u" then solve?

A little to fast but excellent keep up the good work greetings from mexico

Thanks!

Hello. I was confused why you don't use closed bracket instead of parentheses. What if we get the zeros of the absolute values as a solution? (Like in the third question when you construct table) Please reply as soon as possible.

23:37 so in the lower part of the table, will the order always be : Neg. Pos. Pos Neg. Neg. Pos…? I’m not trying to fully understand, (since that’s a bit beyond my paygrade) but I’m trying to memorize the process since it’s easier

thanks!

but if have got both 2 equations correct we take the 4 equations or what?

gr8 video

where are you getting those intervals?

What digital board did you use for this video?

How to plot the values of x in a number line?

Is this for Pre-Algebra or Algebra 1?

Could you please confirm this, because I think I found an easier method of solving the questions with 2 absolute values and the extra bit but the method makes no sense. So basically I tried to just put the extra bit on one side of the equation and the 2 absolute values on one side and made one equation with positive value of the extra bit and one equation with the negative value of the extra bit, taking the absolute values as a positive value. For each question that i tried it had worked, could you please explain why

Hi i dont know if you are still seeing these comments, but im struggling to get the part where i find x for both equations, how do i know if there is a solution or no? Now that seems to depend on conditions but how do i know which conditions do i need to set?

we have the same answer but there are times that, when i tried to verify it through computations, it's giving me the wrong answer. Can you please make a video where you verify the answer? I just need it ty

|x-3|+|x-2|+|x-1|+|x+1|+|x+2|+|x+3|+|x|=12. I'm using a similar strategy as in 11:20 but I'm wondering if there is a simpler way?

wat if the x cancels out?

i was waiting to get stick bugged

what????????/ confuse method is there any way solving in case method

But why did the department of education remove the absolute values from the high school syllabus in South Africa? 😢😢😢

9:00

can you help to solve this one |х-2|+|х+4| - |х-3| = 5 ???

22:24 why neither included? shouldn't they be included somewhere.

👌

sorry its correct sorry for misconception

Need more subs

Fellow student here! Very annoying topic indeed.

lol your two looks like a derivative symbol. nice lecture though
