Aim: How do we multiply rational expressions?

Homework:
Complete handout even # problems. Answers to be provided by Michelle from my 9th period. Click on Aim above for answers.

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

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 where possible.
4. Multiply the remain terms in the numerator and in the denominator.
If the operation between the two fractions is division,

  1. Keep the first fraction as is.
  2. Change the operation to multiplication
  3. Invert (flip) the fraction and follow the 4 steps for multiplication
