Suppose your quadratic polynomial is $f(x).$ Since $(x + 2)(x  1)$ is a quadratic polynomial the remainder after dividing $f(x)$ by $(x + 2)(x  1)$ must be a linear polynomial which means that there is a polynomial $g(x)$ and numbers $a$ and $b$ so that \[ f(x) = g(x) (x + 2)(x  1) + ax + b.\] Can you complete the problem now? Write back if you need more assistance,
