It is not necessary; checking is only a way to verify your answer. If the check does not work out, it means you made an algenbraic error somewhere. Checks can verify one answer, but will not prove that other roots of the equation do not exist.

To see if your answer is correct, take the derivative. Itis -(1/2)/(x+1) +(1/2)/(x-1) = [-(1/2)(x-1) + (1/2)(x+1)]/(x^2 -1) = 1/(x^2-1) Your riginal integrand is equal to 2/(x^2-1), so your answer seems to be off by a factor of 2.
