Copy homework assignment into planner. 5.Use a white board to complete any bell work that is assigned.

2. Lesson 9: Multiplying and Dividing Polynomials

3. Student Outcomes The student will… understand that the product of two polynomials produces another polynomial; students multiply polynomials. Homework: page S.45 Reg. #1:a-n (skip i), #2:a-e

4. Bellwork 1.Evaluate the expression when x = -3 : a. -64c. 68 b. -40d. 336 2.Evaluate the expression: −6x2−4x+2−6x2−4x+2 ( 2x + 3y − 9 )+( 4x 2 + x − 8y + 2 )

5. Exercise 1: Gisella computed as follows: Can you explain what she is doing? What is her final answer?

6. Use a geometric diagram to compute the following products: What do you notice about the terms along the diagonals in the rectangles you drew? (answer) Now complete c and d on your own.

7. Exercise 2: Work Exercise 2 independently and then compare answers with a neighbor. Multiply these polynomials using the distributive property:

8. Exercise 3:

9. Closing Is the product of two polynomials sure to be another polynomial? Is a polynomial squared sure to be another polynomial (other integer powers)?

10. Exit Ticket 1. Must the product of three polynomials again be a polynomial? 2. Find.
