2. Quiz 5-1 1. Simplify 3. Simplify: 2. Simplify

3. Section 5-3 Add, subtract, multiply Polynomials

4. “Like” Terms Which of these terms (if any) are “like” terms? Simplify (add, subtract, multiply, divide)

5. Your Turn: simplify 1. 2.

6. Multiplying Polynomials (x + 3)(2x – 1) = ? key concept Each term inside one set of parentheses is multiplied by every term inside the other parentheses.

7. Your Turn: Multiply 3. 4. 5.

8. Multiplying Polynomials How do you multiply 2 * 3 * 4 three numbers? three numbers? 6 * 4 = 24 OR: 2 * 3 * 4 12 2 * = 24 OR: 2 * 3 * 4 8 * 3 = 24 Pick 2 factors, multiply them to get a product, then multiply the product by the then multiply the product by the last factor (associative property). last factor (associative property).

9. Multiplying Polynomials (x – 1)(2x + 3)(3x – 2) = ? = [ (x – 1)(2x + 3) ] (3x – 2) How do you multiply three binomials? Pick 2 factors, multiply them to get a product, then multiply the product by the last factor  associative property. multiply the product by the last factor  associative property.

10. Multiplying Polynomials How do you multiply these? Remember “long” multiplication?

11. Multiplying Polynomials How do you multiply these? Align “like terms” in a vertical line so it is easier to add them together. so it is easier to add them together. (x – 1)(2x + 3)(3x – 2) = ?

12. Your Turn: Simplify ( Multiply the Binomials and combine like terms) 6. 7.
