III. Distinct Quadratic Factors

Resolve into partial...

4.) (3x^3 + 8x^2 + 6x - 2) / (x+2)(x+1)(x^2+2)

And the rule

= A / (x +2) + B ( x+1) + (Cx + D)/(x^2 + 2)

the only part i cant seem to find is by solving A,B,C and D

3 = A + B + C

8 = A + 2B + 3C + D

6 = 2A + 2B + 2C + 3D

-2 = 2A + 4B + 2D

can u check if thiss correct?
