Algebra: Chapter 10, Lesson 3, page 439.
Dividing Rational Expressions
We divide rational expressions using the same techniques we used in Chapter 10-2. The only difference is that we have to change the division sign in front of the 2nd term to a multiplication sign and FLIP (use the reciprocal) the second term upside down.
For example, `(8n^5)/3 ÷ (2n^2)/9` becomes
`=(8n^5)/3⋅9/(2n^2)` which simplifies to `=(72n^5)/(6n^2)=12n^3
Remember to factor the DIFFERENCE of 2 SQUARES (binomial squares) and TRINOMIAL SQUARES as well as use the BOX METHOD of FACTORING.
