Lesson Review:Remember that a rational expression is a fraction. The objective in this lesson is to divide two algebraic fractions and reduce the answer to the most simplifed form.These expressions can be monimials or polynomials in factored or unfactored form.

THE 3 STEP PROCEDURE FOR DIVIDING IS AS FOLLOWS:
1. Keep the first fraction
2. Change the sign of the operation to multiplication
3. Flip(riciprocal) the 2nd fraction
4. Follow the 4 steps used for multiplying

THE 4 STEP PROCEDURE FOR MULTIPLYING IS AS FOLLOWS:
1. Factor the numerator of each fraction if possible.
2. Factor the denominator of each fraction if, possible.
3. Reduce like terms in the numerator and denominator by dividing the factors OR cross cancelation.where possible.
4. Multiply the remaining terms in the numerator and in the denominator.
