Find Remainder of 4x^3-3x^2-8x+4 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 4x^3-3x^2-8x+4 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 4x^3-3x^2-8x+4 by x+1 using Remainder Theorem?
Let p(x) = 4x^3-3x^2-8x+4
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) = 4x^3-3x^2-8x+4 .
= (4)+(-8.x)+(-3.x^2)+(4.x^3)
By putting x = (-1) we can rewrite it as
= (4)+(-8.(-1))+(-3.(-1)^2)+(4.(-1)^3)
= (4)+(8)+(-3)+(-4)
= 19
∴The remainder of given polynomial is 19.
