2.3 Real Zeros of Polynomial Functions: Synthetic Division Synthetic Division
When dividing polynomials, there is a shortcut method that you can use called synthetic division. To divide 3 + 2 + + by - , you will follow the pattern as shown below. The vertical pattern is to add terms; the diagonal pattern is to multiply by "k" as you will see below. Example 1: Solve with synthetic division. (4 - 102 - 2 + 4) ? ( + 3)
Example 2: Solve with synthetic division. (53 + 82 - + 6) ? ( - 2)
Example 3: Solve with synthetic division. (23 + 13 - 10) ? ( + 4)

2.3 Real Zeros of Polynomial Functions: Remainder Theorem Remainder Theorem
The Remainder Theorem says, "If a polynomial () is divided by ( - ), then the remainder is (). Example 1: Use the Remainder Theorem to evaluate () = 33 + 82 + 5 - 7 when = -2.
Example 2: Use the Remainder Theorem to find each function value given: () = 43 + 102 - 3 - 8
Find: (-1), (4), (1) , (-3)
