1. 1. Chapter 7 Multiplying and Dividing Polynomials Review
2. 2. Checklist Model multiplication of monomial times a monomial, or monomial times a binomial using algebra tiles or an area model. Write a multiplication statement that represents an algebra tile model or an area model.
3. 3. Model division of monomial by a monomial, or binomial by a monomial using algebra tiles or an area model. Write a division statement that represents an algebra tile model or an area model.
4. 4. Simplify expressions to find products and quotients without using models Solve word problems involving polynomial multiplication or division.
5. 5. Model multiplication of monomial times a monomial, or monomial times a binomial using algebra tiles or an area model. Model -2x(3x -2) using both an area model and an algebra tile model Algebra tile model Area model
6. 6. Write a multiplication statement that represents an algebra tile model or an area model.
7. 7. Model division of monomial by a monomial, or binomial by a monomial using algebra tiles or an area model. 2 Model (4x + 8x) ÷ -2x using both an algebra model and an area model
8. 8. Write a division statement that represents an algebra tile model or an area model. ? -4x 4xy - 12x
9. 9. Simplify expressions to find products or quotients without using models Simplify to find the products (show all steps using the distributive property) a) 3x(-2x + 4) b) (4.5x - 3)4x
10. 10. Simplify to find the quotients (show all steps) a) 2 15y - 12y 3y b) (-10x2 + 4x) ÷ -4x
