Find Remainder of x^2-2x+4 by x+2 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^2-2x+4 by x+2 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^2-2x+4 by x+2 using Remainder Theorem?
Let p(x) = x^2-2x+4
The zero of x+2 is = -2.
So after P(x) is divided by x+2 we get the remainder i.e. P(-2).
Now, p(-2) = x^2-2x+4 .
= (4)+(x^2)+(-2.x)
By putting x = (-2) we can rewrite it as
= (4)+((-2)^2)+(-2.(-2))
= (4)+(4)+(4)
= 12
∴The remainder of given polynomial is 12.
FAQs on Remainder Theorem of x^2-2x+4 by x+2
