Hello. I'm trying to find partial fraction decomposition of 1/(x**2-2*b**2) I use f.partial_fraction(var), but I don't get the result.

How can I get an exact answer over the reals in general case?

sage: 1/product([(x-u[0])^u[1] for u in (x**2-2*b**2).roots(x=x)])
-1/((sqrt(2)*b + x)*(sqrt(2)*b - x))
