What is the remainder when a^3 - 4 is divided by a+2?
a)0
b)-6
c)-2
d)-12

The remainder is -12. Choice d)

Step-by-step explanation:

The Remainder Theorem

The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).

We have the polynomial

To evaluate the remainder when P is divided by a+2, we only have to find P(-2):

The remainder is -12. Choice d)
