    Partial Fraction Problem

    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))

    Re: Partial Fraction Problem

    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?

    Re: Partial Fraction Problem

    Found the problem. I was not multiplying D by 3 when getting rid of the denominators. Thanks for your help hedi
