# Remainder Theorm, i'm stuck =( watch

1. I really can't work out this question, could anyone help me?

f(x) = x^3 + ax^2 + bx + 6

When f(x) is divided by (x-1) the remainder is 24,
When f(x) is divided by (x+2) the remainder is also 24.

Use the Remadiner theorm to fine the numberical values of a and b.

I just don't understand how to work it out =( Thanks everyone.
2. so f(x) leaves a remainder of 24
if only it was 24 smaller...
