In this video we learn how to divide rational expressions, which are fractional expressions in which both the numerator and denominator are polynomials. We'll turn the division problem into a multiplication problem by taking the reciprocal of the divisor and switching the division to multiplication.

Before we do the multiplication, we should factor the numerator and denominator of both fractions as much as we can in order to see if there's anything we can cancel within either fraction or across both fractions.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
