MR. Organic Chemistry Tutor, thank you for another off the chart's video/lecture on Multiplying Rational Expressions in Algebra/Algebra Two. There is high probability of making errors while multiplying/factoring rational expressions, so students must pay close attention to all algebraic operations.
today is the day before my algebra 2 unit 2 test, one of the most difficult algebra tests i have yet to take. it is around 85 points for this first section, and i was really stressed about it until i remembered your videos. my teacher is rarely at school, so often, the most important lessons are taught through google classroom and a worksheet. i find myself pulling my hair out trying to teach myself these things, so when i find a video you make on the topic, i am flooded with relief. i have been on an algebra 2 video binge for the past few hours, and i have learned more from you than i have this year. thank you so much. you help so many people, including myself.

2 жыл бұрын
Exactly! 3/3=1 -5/-5=1 10x/10x=1 (x+2)/(x+2)=1 Etc. If you ever have the exact same thing on the top and bottom, they cancel out and equal = 1
is the point of discontinuity means restriction???

@aidanpotts7157

Here he factored out a 10x and also factored out the trinomial. This is what happened. He had 10x^3 -70x^2 +120x --> 10x(x^2 - 7x +12x) then factored the (x^2 -7x+12x) term to be (x-3)(x-4) so the final factored expression was 10x(x-3)(x-4). Hopefully that made sense!

Im kinda confused when do we use the difference of perfect squares? Or how do i know that i have to use it to solve this
@aidanpotts7157
3 жыл бұрын
Difference of perfect squares is a "special pattern" basically a way of simplifying expressions. The more questions you do the quicker you will recognize these difference of squares and can write them in the form of (a+b)(a-b) also to get the value of a^2 - b^2 you can just expand the (a+b)(a-b) term out and you will see that the ab term cancels!
