Make use of this Remainder Theorem Calculator & calculate your lengthy polynomials remainder problems easily by just entering the input ie., 5x^3+x^2+x-8 by x+1 in the box & get the result ie., -13 in no time.

**Ex: ** x^2+2x+1,x+1 (or) x^2-1,x-1 (or) x^3-1,x+1

Given values are

f(x) = 5x^3+x^2+x-8

x = -1.

Given Polynomial is 5x^3+x^2+x-8 .

= (-8)+(x)+(x^2)+(5.x^3)

By putting x = (-1) we can rewrite it as

= (-8)+((-1))+((-1)^2)+(5.(-1)^3)

= (-8)+(-1)+(1)+(-5)

= -13

The remainder of given polynomial is -13.
