Question

Without using the long division method, determine the remainder when the polynomial 4x

+ 2x4 - x3 + 4x2 – 7 is divided by (x + 1).

Answer 1

Answer:

put x :-1 in the following equation

Answer 2

Step-by-step explanation:

by remainder theorem,

x+1 = 0

x = -1

put it in given polynomial

2(-1)^4-(-1)^3+4(-1)^2-7

2+1+4-7

7-7 = 0

remainder is zero
