1. Bell Quiz Combine like terms: 1.(3x 3 +7x 6 +3)+(-5x 6 +9+5x 3 ) 2.(6x 3 +8x 2 +8)-(7x 3 -7x 2 +3x-8) 3.(3x 2 -5x+7)+(4x 2 +8x-3) 4.(-5x 2 +7x-2)+(2-3x+4x 2 ) 5.Write the polynomial so that the exponents decrease from left to right: -4x 2 -3x-3x 4 -2

2. 9.2 Multiplying Polynomials using the Distributive Property You will review the distributive property with polynomials You will learn how to undistribute working with polynomials Page 33 in the workbook

3. 4 Review: Distributive Property 4

4. Distribute

7. Distribute, then combine like terms

9. But what did it look like before distributing? 5 5 before This is called FACTORING!

10. Timeout: a review of GCF Factors : pairs of numbers that can be multiplied together to obtain the given number 9b: 12: 4ab: 6b: 9b: 1 3 9 b 12: 1 2 3 4 6 12 9x 3 : 6x 2 : 12x: 4ab: 1 2 4 a b 6b: 1 2 3 6 b 9x 3 : 1 3 9 x x x 6x 2 : 1 2 3 6 x x 12x: 1 2 3 4 6 12 x

11. 9b: 1 3 9 b 12: 1 2 3 4 6 12 Try to undistribute/factor: 9b+12

12. 4ab: 1 2 4 a b 6b: 1 2 3 6 b Try to undistribute/factor: 4ab+6b

13. 9x 3 : 1 3 9 x x x 6x 2 : 1 2 3 6 x x 12x: 1 2 3 4 6 12 x Try to undistribute/factor: 9x 3 +6x 2 -12x

14. 10pq 2 : 15pq: 5q: Try to undistribute/factor: 10pq 2 -15pq+5q

15. 14a 3 : 7a 2 b: 49ab 2 : Try to undistribute/factor: 14a 3 -7a 2 b+49ab 2
