12-1 Simplifying Rational Expressions Objective: To simplify rational expressions. Standard 12.0

Excluded Values Excluded Values: values that make the denominator zero (because we cannot divide by zero). Always find the excluded values BEFORE you cancel anything out. Examples: State the excluded values

Steps 1. Factor top and bottom of fraction separately 1. GCF 2. Binomial: Difference of 2 squares 3. Trinomial: X-Box, Perfect Square trinomial 2. Find excluded values (denominator 0) 3. Cancel out factors (what top and bottom have in common)
