Multiplying and Dividing Rational Expressions
- To simplify an algebraic fraction, factor the numerator and denominator completely. Then cancel common factors. When multiplying or dividing, do the same thing – factor all the numerators and denominators, then cancel common factors.
- If two factors in the numerator and denominator look almost the same, factor –1 out of either of the factors and see if you get two identical factors.
