Answer:

Remainder is 13

Step-by-step 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
