Re: Is Apart[ .. ] the correct way for denominator splitting?

The reason Apart doesn't work is because x^2-1 can't be factored with
rational coefficients. You can however use the Extension feature of
Factor to do what you want:

Apart2[exp_, x_] := Apart[Factor[exp, Extension ->
    x /. Solve[Denominator[exp] == 0, x][[1]]]]
