What have you tried? Here's a quick summary of the steps...

step 1:
4x^2-1/2x(x+1)^2 = A/2x + B/(x+1) + C/(x+1)^2

step 2:
4x^2-1/(x+1)^2 = A and evaluate at x=0

Step 3:
*Solve for C before you solve for B:
4x^2-1/2x = A(x+1)^2/2x + B(x+1) + C and evaluate at x=-1

Step 4:
Then, differentiate the equation in the step 3 with respect to x

Step 5:
Finally, evaluate equation in step 4 at x=-1

You should now have all your constants, A, B and C
