Quiz Use Synthetic Substitution to evaluate: 3.What is the “end behavior” for: 2. Simplify When x = 2 In other words:

Section 5-3 Add, subtract, multiply Polynomials

“Like” Terms Which of these terms (if any) are “like” terms?

Your Turn: Subtract the polynomials 1.

Multiplying Polynomials (x + 3)(2x – 1) = ? What is the key concept when multiplying polynomials? polynomials? Each term inside one set of parentheses is multiplied by every term inside the other parentheses. (x – 1)(2x + 3)(3x – 2) = ?

Your Turn: Multiply the Polynomials 2.

Special patterns There is an error in your green books. (sum and difference) (a + b)(b – a) should be: (a + b)(a – b)

Special Products Product of a sum and a difference. (x + y)(x – y) xy - xy

Your Turn: Multiply 3.

Special Products Square of a sum. (x + y)(x + y)

Special Products Square of a sum. (x + y)(x + y)

Your turn: 4. Simplify (2x + 3)(2x + 3) = ?

Special Products Square of a difference. (x - y)(x - y)

Special Products Square of a difference. (x - y)(x - y)

Your Turn: Multiply 5.

Special Products Cube of a sum.

Special Products Cube of a difference.

Your Turn: Multiply 6.
