Adding, Subtracting, Multiplying, & Dividing Rational Expressions
Objective: Add, subtract, multiply, divide, and simplify rational expressions.

Example #1 Multiplying & Dividing Rational Expressions
Multiplying: Factor first, multiply straight across, cancel common factors. A.)

Example #1 Multiplying & Dividing Rational Expressions
Dividing: Factor first, multiply by the reciprocal of the second fraction, and cancel common factors. B.)

Example #2 Adding & Subtracting Rational Expressions
To add or subtract rational expressions, they must have the same denominator. If not, factor to compare denominators and find the least common denominator. A.)
