I can see that ,

because,

But when I try to use partial fractions

This doesn't seem to work at all. Basically this gives inconsistent values of A and a value of zero for B. Am I approaching the method of partial fractions wrong? Since there isn't a squared term on the right, A must be zero right?

EDIT: LOL, I know where I'm going wrong. I need to use As+B in the denominator because the one factor is quadratic. Sorry for wasting time.
