Question 403717
I don't know if you mean {{{(x^2 - 1)/(x - 3) = 0}}} or {{{x^2 - 1/(x-3) = 0}}} or {{{(x^2 - 1)/x - 3 = 0}}}. In any case, you can use LCD and write the equation as some fraction a/b = 0, and solve for a = 0. Be sure to check that if the numerator equals zero, the denominator is nonzero.
