partial fraction problem

Question

I have thought for a long time but general method is not working :

$$\frac{s^2+2}{(s+2)^2(s^2+2s+2)^2}$$

Thanks for all help.

You miss one $)$ in the expression. – Claude Leibovici Nov 30 '14 at 13:18 — Claude Leibovici, Nov 30 '14 at 13:18

Hint:

$$\frac{s^2+2}{(s+2)^2(s^2+2s+2)^2} = \frac{As+B}{(s+2)^2}+ \frac{Cs^3+Ds^2+Es+F}{(s^2+2s+2)^2}$$
