1. Warm Up
Simplify the expression by using distributive property and then combining like terms. x(x + 5) + 4(x + 5)

2. 10.2 Multiplying Polynomials
Algebra 1
10.2 Multiplying Polynomials

3. Take a look at our warm up
x(x + 5) + 4(x + 5)

4. Use the Distributive Property to find the product
(x + 1)(x + 2)
(x – 2)(x + 4)
(2x + 1)(x + 2)

5. F O I L

7. Use the FOIL method to find the product.
(x + 1)( x – 4)
(2x – 3)(x – 1)
(x – 2)(2x + 1)

8. Multiplying Polynomials
To multiply two polynomials that have three or more terms, remember that each term of one polynomial must be multiplied by each term of the other polynomial. Vertical Format Horizontal Format

9. Vertical Format
(x + 1)(x2 + 3x – 2)

10. Horizontal Format
(x – 4)(x2 + x + 1)

11. Find the product of the polynomials
(x + 5)(x2 – x – 3)
(2x – 1)(2x2 + x – 3)
(3x2 + x – 4)(2x – 3)
