1. Aim: How do we multiply monomials and polynomials?

2. Agenda -Homework review -Do now review -Quick review about exponents -Multiplying monomials -Multiplying polynomials

3. Vocabulary Monomial Polynomial

4. All powerpoints will be color coded as follows: RED means COPY (write it down!) BLACK means READ YELLOW means READ and REFLECT BLUE means DO GREEN means NEW ASSIGNMENT (might need to be written down in your planners)

5. Homework # 3 due 9/16

6. Check your homework # 2 answers:

8. Quick review about exponents!

9. Practice!

10. Multiplying variables

11. Let’s see it with a real numbers!

12. Monomial times a monomial

14. Let’s try together!

15. Practice!

16. Monomial times a polynomial For multiplying a monomial with a polynomial, use the distributive property. (5x 3 )(4x + 6x 2 ) 1) Make a rainbow with the number outside the parentheses to the first term! Distribute (multiply) the number outside the parentheses to the first term. (5x 3 )(4x + 6x 2 ) 5x 3 (4x) +

17. (5x 3 )(4x + 6x 2 )

18. 3) Now we are multiplying monomials! Remember! – Multiply the constants – Multiply the variables – Put the constants and variables together!

19. Let’s try together! 3x 2 (2x +3)

20. Try on your own! 1.9x(5x +3) 2.3x(x 4 – 4) 3.x( x 3 + 3) 4.3x(x 4 – 4y) 5.x( xy 3 + 3y)

21. Hand this in! On a separate sheet of paper with your first and last name on it answer the following: 1.(x 2 + 3x – 2) + (-x 2 + 4x – 2) 2. (-8x 2 + 4x – 7) - (3x 2 - 5x +2) 3.(x 3 ) (x 2 ) 4.(3x 2 ) (7 x 4 – 3x )
