2. Warm-up 6-1

3. Lesson 6-1 Simplifying Rational Expressions

4. The quotient of two polynomials is called a rational expression.

5. Simplifying Expressions - Identical factors on top or bottom cancel - Identical factors on top &bottom in multiplication cancel Factor polynomials

6. Rules for Multiplying and Dividing Rational Expressions ALWAYS FACTOR FIRST!

7. Example 1:

8. Example 2:

9. Warm-up 6-2 1. 2.

10. Lesson 6-2: Adding & Subtracting Objectives: Add and subtract rational expression with like and unlike denominators

11. Adding and Subtracting Rational Expressions, Denominators Equal

12. Example 1:

13. Adding or Subtracting Two Rational Expressions, Denominators Unequal ► Factor first ► Multiply a fraction by factor in other denominator it doesn’t have

14. Example 2:
