What is the Remainder Theorem?

Back

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

How do you perform synthetic division?

Back

Synthetic division is a simplified form of polynomial long division. It involves using the coefficients of the polynomial and the value of c to find the quotient and remainder.

What is the significance of the roots of a polynomial?

Back

The roots of a polynomial are the values of x for which the polynomial equals zero, and they correspond to the factors of the polynomial.

Front

What is the relationship between factors and zeros of a polynomial?

Back

If (x - c) is a factor of a polynomial, then c is a zero (or root) of that polynomial.
