### What is the Remainder Theorem?

In mathematics, a remainder theorem states that when a polynomial f(x) is divided by a linear factor x-a, then the remainder of the polynomial division is equal to f(a).
We know that, Dividend = (Divisor x Quotient ) + Remainder
If f(x) is a divident, (x-a) is divisor, q(x) is a quotient, r(x) is a remainder,
It can be written as:
f(x) = (x-a)·q(x) + r(x)

### Example

Question:
Determine the remainder when the polynomial 3x2-1 is divided by x-1.
Solution:
Given: Dividend = 3x2-1
Divisor = x-1
We know that,
f(x) = (x-a)·q(x) + r(x)
When 3x2-1 is divided by x-1, we get the quotient 3x+3, and remainder 2.
