What is the Remainder Theorem?

Back

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

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

Back

If the remainder when dividing the polynomial by (x - c) is zero, then (x - c) is a factor of the polynomial.

What is the Factor Theorem?

Back

The Factor Theorem states that (x - c) is a factor of a polynomial f(x) if and only if f(c) = 0.

How do you use synthetic division to show that (x - 5) is a factor of a polynomial?

Back

Perform synthetic division with 5 as the divisor; if the remainder is 0, then (x - 5) is a factor.
