5‐4 Synthetic Division

*You must be dividing by a linear expression and the leading coefficient (first number) must be a 1.

**In synthetic division ‐‐> Add instead of subtract!

Example:  Use synthetic division to divide the polynomials.

(x3 + 4x2 + 6) (x + 3) x2 + x ‐ 3 R 15

Divide.x2 ‐ 4x + 3

Useful for solving polynomials if factors are known.
