    Partial Fraction Decomposition

    I'm having trouble with this one problem. The answer I'm getting is apparently not correct but I can't find my error.

    This is a refresher for me why don't you have to multiply the denominator by the other two denominators?

    Re: Partial Fraction Decomposition

    Because x^2+1 is already a factor of (x^2+1)^2, so the LCD is just x(x^2+1)^2 as opposed to x(x^2+1)(x^2+1)^2
