## Homework Statement

(x^3+4)/((x^2-1)(x^2+3x+2))

## Homework Equations

## The Attempt at a Solution

Try separating them into Ax+B and Cx+D, then expand until

(A+C)x

^{3}+(3A+B+D)x

^{2}+(2A+3B-C)x+(2B-D)

then, I was stuck. I can't find any value for A,B,C or D. Is my attempt correct or is there other way to solve it?
