## Polynomials II: Factor and Remainder Theorems **What is the Remainder Theorem?** It states that when a polynomial $P(x)$ is divided by a linear expression $(x - a)$, the remainder is $P(a)$. **What is the Factor Theorem?** It states that if $P(a) = 0$, then $(x - a)$ is a factor of the polynomial $P(x)$. This means if the remainder is zero, the linear expression divides the polynomial perfectly [Preview only]
