# Polynomial Division - The Factor and Remainder Theorems

# Section 1: Factor and Remainder Theorems, Long Division and Synthetic Division

It would be helpful to review factoring principles for binomials and trinomials.

In this module we will study two important results on polynomials - the Factor Theorem and the Remainder Theorem.

The **Remainder Theorem **asserts that the value P(c) of a polynomial at a point c is the remainder on dividing the polynomial P(x) by (x - c). The quantity (x - c) divides P(x) evenly if and only if P(c) = 0, in which case, (x - c) is a **factor of P(x)**.

The **Factor Theorem** asserts that c is a zero of a polynomial if and only if (x - c) is a factor of the polynomial.
