# Remainder Theorem Calculator

Remainder theorem can be used to determine the zero of the polynomial . If dividing the polynomial by factor x - a gives the remainder r = 0 then x - a is one of the factor of the polynomial .In other words x = a is the zero of the polynomial.

Definition:

When you divide a polynomial f(x) by x - a the remainder r will be f(a) . Whenever we want to know the remainder after dividing by x-a ,calculating f(a) will give the remainder.
