Use synthetic division and the remainder theorem to find P(a)

I am absolutely confused on how to do this,


Use synthetic division and the remainder theorem to find P(a)

P(x) = x^3 + 4x^2+4x a = -2




When i evaluated (a) for x i ended up with 0 which is what the book said, but i'm sure where the synthetic division comes into play?

Your class and your textbook were supposed to have covered this topic before assigning you homework on it. To learn how the Remainder Theorem allows one to "evaluate" a polynomial by doing the division, try here.
