What is the Remainder Theorem Calculator?

The Remainder Theorem Calculator allows you to quickly determine the remainder when a polynomial is divided by a linear divisor of the form x−cx – cx−c. By entering the polynomial coefficients in descending order of degree and the value of ccc, the calculator evaluates the polynomial at x=cx = cx=c and gives the remainder directly. This eliminates the need for long division, making it ideal for students and professionals who need fast verification of factors, roots, or polynomial simplifications.

How to Use:

1. Enter Coefficients: Input the polynomial coefficients in order from highest to lowest degree, separated by commas.
2. Enter ccc Value: Input the value for ccc in the divisor x−cx – cx−c.
3. Click “Calculate”: The calculator will evaluate the polynomial at x=cx = cx=c and display the remainder.
4. Interpret Results: The remainder tells you the value of the polynomial when x=cx = cx=c, confirming whether x−cx – cx−c is a factor (remainder = 0) or not.
