Find Remainder of x^3+4x^2-8x-10 by x+1 using Remainder Theorem
The Remainder Theorem is an approach to Euclidean polynomial division. According to this theorem, dividing a polynomial P(x) by a factor (x - a), which is not an element of the polynomial, yields a smaller polynomial and a remainder. Here you can check the answer for Find Remainder of x^3+4x^2-8x-10 by x+1 using Remainder Theorem.
Ex: x^2+2x+1,x+1 (or) x^2-1,x-1 (or) x^3-1,x+1
How to Find Remainder of x^3+4x^2-8x-10 by x+1 using Remainder Theorem?
Let p(x) = x^3+4x^2-8x-10
The zero of x+1 is = -1.
So after P(x) is divided by x+1 we get the remainder i.e. P(-1).
Now, p(-1) = x^3+4x^2-8x-10 .
= (-10)+(x^3)+(-8.x)+(4.x^2)
By putting x = (-1) we can rewrite it as
= (-10)+((-1)^3)+(-8.(-1))+(4.(-1)^2)
= (-10)+(-1)+(8)+(4)
= -5
∴The remainder of given polynomial is -5.
