Multiplying & Dividing Rational Expressions

Simplified form of a rational expression - Means the numerator and denominator have NO common factors. To simplify: 1) Factor everything. 2) Cancel common factors. ***Remember-only cancel factors don’t cancel addends.

Examples Examples: Simplify.

Multiply To multiply: 1)FACTOR everything. 2)Cancel common FACTORS. 3)Multiply the numerators then multiply the denominators.

Multiply These are opposites. Factor a negative out of one of them.

Divide: Remember to divide fractions you multiply by the reciprocal. (Flip the one you are dividing BY then multiply.) To divide: 1)Flip the divisor. 2)FACTOR everything. 3)Cancel common FACTORS. 4)Multiply the numerators then multiply the denominators.
