How do you 1/(x^2-1) in partial fractions?
The solution
Fraction decomposition
[src]
1/(2*(-1 + x)) - 1/(2*(1 + x))
$$- \frac{1}{2 \left(x + 1\right)} + \frac{1}{2 \left(x - 1\right)}$$
1 1 ---------- - --------- 2*(-1 + x) 2*(1 + x)
Combinatorics
[src]
1 ---------------- (1 + x)*(-1 + x)
$$\frac{1}{\left(x - 1\right) \left(x + 1\right)}$$
