I'm just trying to solve some like problems, and your videos are the best I've seen so far. Just note, that explaining math is one of your strong points. Thank you.

[@gabriesachilles3933]

Yeah! He is our real math teacher who can explain us every detail than our original teachers!

[@shannonmcdonald7584]

You were my first algebra tutor when I began A1 last winter. I remember when this video was difficult. 6 hrs a day for months and not I'm beginning calculus. Did your Power Rule of Integration this week asking with derivatives and limits. All this to say thank you, my guy.

MR. Organic Chemistry Tutor, thank you for another monster video/lecture on Dividing Rational Expressions in Algebra Two. I really enjoyed this topic on rational expressions.

believe it or not i've watched 29 videos of yours today only...and imma keep going.

[@TrajectoryT]

I feel this

[@GODiKING]

0:00 Focus on dividing Rational Expression and determine the excluded value 11:24 Put the denominator on the outside and the numerator on the inside

[@diyacries]

2:21 how come we didn't cancel the (x+3) w the (x+3)? there are the same

[@Itsfaymi00]

because they are both in the denominator u cant cancle them unless they were upbove wach other or there is multiplication sign between two expressions and one is denominator and the other one Is numerator in the other expression ( hope that helped english is not my first language )

[@francislibresupnet5219]

Thank you for this God's product, now I can easily understand all the topics

[@redmoosekiller]

This is crazy I didn’t know you learned this so early I guess I forget, I’m in my second year of college and have an exam tomorrow

Good video, nice explaination like my math teacher

[@_Moonjiro]

These really hard to understand and the alphabet I can't understand it a little bit but still thankful to this video..It help me to know how to solve the expression and so I can now answer my math subject without using apps

[@provincelife1649]

Thank you 👍

[@marialandivar3155]

At 6:32 how did he get 2(x-5)/3? what did he simplify or divide to get there? Somebody please explain!? Whats wrong with the volume? It goes up and down. I can barely hear!

[@blueguy5514]

Hi

[@nootnootah]

9:14 never seen this before. i would've factored the top and reduced it. but the long division does look cool

[@issakeny2772]

at 11:50 why did he add the extra 0x? I'm not following. Everything else in this video did make sense though

[@coolshapes]

Just as a placeholder for the long division format to work

[@vwa9832]

I get it, its just a lot of work lol

[@carmillaC10001]

Wait so what is the point of Excluding Values?

[@Astrogod028]

2:11 in this case, why didnt you just do x + 5^2?

[@02REVENGE]

How do u get a 2 for B in the sum of perfect cubes when the 8 is the B?

[@v.ncent4]

8 isn't B is B cubed, so if you use a cube root on the 8 its 2

[@blion_oCeAn]

THANKS IM NOW CONFIDENT DOING MY EXAM

[@MineCraft-sb3zz]

In the last example could we further factor 4x^2+8x+26 into x^2+2x+7?

[@kylezibell4925]

lol no

[@itzsebbie9637]

I owe you so much bro im gonna pass math cuz of you

[@ShinRu11]

Only here beacause i was late at the lesson, but thanks to this guy i will be able to answer at our quiz 💀🙏

[@MineCraft-sb3zz]

In 6:25 why did he factor out the 6(x^2+4) using the cube identity even though it is not raised to 3 or cube rather.

[@jamesjames304]

It's been 4 years, but to answer your question, he did not use the sum of two cubes-rather he used the sum of two squares of (x²-4) which is equal to (x+2)(x-2). Additionally, the 4/6 is equal to 2/3.

[@arianagalindo8728]

why did you take out a negative when multiplying at 9:37 ?

[@tobitcalimutan2924]

I agree

[@tobitcalimutan2924]

because its division like this Ex. 9 L (Upside down sorry) 3 9 L27 - (this!)

[@kimberlygomez130]

he made the 12 positive in (8x²-12x ) because there was a negative outside of the parentheses,, therefore u have to flip both signs making 8x² into -8x² and -12 into positive 12

[@kimberlygomez130]

i hope that maybe helped?😭

[@tashspond]

Quick question, on the first equation, doesn’t the top (over 1) also need to be multiplied by 4 before the expressions can become a whole?

[@XxMesmerized1LOvEXx]

[@fatimatanveer8529]

Why can't we cancel (x+3) and (x+3) at 2:20?

[@michy_documents]

You cannot cancel across, only diagonal and/or vertical. Since the two (x+3) are both in the numerator, you can write them as one and simply square it. It's just the same as (x+3)(x+3). I hope this helps.

[@fatimatanveer8529]
