Intro to the Polynomial Remainder Theorem
The Polynomial Remainder Theorem allows us to determine whether a linear expression is a factor of a polynomial expression easily. It tells us the remainder when a polynomial is divided by
\[x - a\] is
\[f(a)\]. This means if
\[x - a\] is a factor of the polynomial, the remainder is zero. It's a neat trick to quickly find remainders without doing long division!
