How do you determine if (x - c) is a factor of a polynomial?

Back

You can determine if (x - c) is a factor of a polynomial by using the Remainder Theorem: if the polynomial evaluated at c is zero, then (x - c) is a factor.

What is the Remainder Theorem?

Back

The Remainder Theorem states that when a polynomial f(x) is divided by (x - c), the remainder is f(c).

How do you perform synthetic division?

Back

To perform synthetic division, bring down the leading coefficient, multiply it by c, add it to the next coefficient, and repeat until all coefficients are processed.
