I've solved many partial fractions, but this one has really puzzled me. There is one term I can't get correctly. Any help would be appreciated!

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

decomposite: A/(x+1)+B/(x-1)+(Cx+D)/(x^2+2)

Thanks hedi. That's the exact approach I took, yet for some reason, I am ending up with the last two terms being negative four and four, when in reality, C should disappear and D should be a negative four. A and B are correct however.

you should get A=-2/3,B=2/3,C=0,D=4/3

what is your difficulty? - November 5th 2012, 12:01 PMMemoNickRe: Partial Fraction Problem
Found the problem. I was not multiplying D by 3 when getting rid of the denominators. Thanks for your help hedi :)
