Question

1. What is the remainder when x³+4x2-2x+1 is divided by x+2 1. What is the remainder when x³ + 4x2-2x + 1 is divided by x + 2​

Answer 1

Remainder is 13

Explanation:

You can apply the remainder theorem here. You just equate the divisor to 0, then substitute the x-value in the expression.

`x^3 + 4x^2 - 2x + 1 \\` then,
`x+2=0\\x=-2`

substitute:

`-2^3 + 4(-2)^2-2(-2) + 1 =13`

Therefore, the remainder is 13
