Factoring and Finding Zeros with Synthetic Division

What does the Factor Theorem state?

• If the polynomial is zero, the remainder is a factor of the divisor.

• If the divisor is zero, the remainder is a factor of the polynomial.

• If the remainder is non-zero, the divisor is a factor of the polynomial.

• If the remainder is zero, the divisor is a factor of the polynomial.
