8-1 Multiplying and Dividing Rational Functions Simplify rational expressions. Simplify complex fractions.
A ratio of two polynomial expressions is called a rational expression Variables in algebra represent numbers, so operations with rational numbers and rational expressions is similar. Factor numerator and denominator If there are common factors, reduce If multiplying rational numbers, the numerator multiplies by the numerator, and the same with denominators. If dividing, reciprocate 2nd or bottom fraction and change to multiplication.
