Question

Find the remainder when the polynomial x3+x2-2x+1 is divided by(x+1)

​

Answer 1

Answer:

Remainder = 3

Step-by-step explanation:

Given

$P = x^3 + x^2 - 2x + 1$

$D =x + 1$

Required

Determine the remainder

$D =x + 1$

Equate to 0

$x + 1 = 0$

$x = -1$

Substitute -1 for x in $P = x^3 + x^2 - 2x + 1$

$P = (-1)^3 + (-1)^2 - 2(-1) + 1$

$P = -1 + 1 + 2 + 1$

$P = 3$

Hence, the remainder is 3
