Partial Fractions

The Attempt at a Solution

I know that I need to use partial fractions. But I don't know how to put it in (A/x)+(B/x)...etc

Would someone please kindly show me how to set up this equation? I've been stuck on the same problem for an hour now.
Thanks in advance to those who can shed some light on this!

You want
\frac{5x^3+ 4x^2- 4}{x^3(x+1)}= \frac{A}{x}+ \frac{B}{x^2}+ \frac{C}{x^3}+ \frac{D}{x+ 1}
