Simplify the RATIONAL Expressions - how well can you factor? 

Now there's a refreshingly positive reply.

hey... the guy provides this FOR FREE so he has to "run his.commercial." There's a slider at the bottom for us who know his thing by heart ao we can skip the intro...

@@tomtke7351 Exactly!

@@cbesthelper404 The man gives us so much wizdom... trudging thru a bit of him selling his product is no problem... besides, you can easily jump thru this by the slider... so what's your problem?

@@tomtke7351 I know. It's free. If someone wants to "fast-forward" through, they can easily do so. All the complaining is quite unnecessary. I appreciated your comment.

Yep, prattles on too much.

Hey, I’m curious. I’ll use chat gpt to find the answer. Hope you don’t mind. Is that a riddle or actual math? (In the sense that you’ll be able to compute your way into the answer)

Literally my thought process

The reason they say that is that Math builds, one concept on top of one already mastered. So, a teacher cannot go all the way back to the beginning each and every time. Once you reach the level of Algebra, it is assumed that you know Pre-Algebra. In this case, this is a rational expression which is introduced to students AFTER the students have studied factoring. So the instructor is focusing on the new topic and is rightfully assuming that the student already knows the earlier topic of factoring. If the student DOESN'T already know it, then whose fault is that? It's the student's responsibility to keep up with the lessons. It wouldn't be fair for the teacher to continue to backtrack when other students are ready to move on. This instructor has created a lot of videos of factoring. That is why he is moving on. You can always go and view his videos on factoring, and then return to this one for greater understanding.
