Assuming that "x2" means x squared (x^2):
x^2 - 4x - 32 = 0
factoring*
(x-8)(x+4) = 0
So the roots are 8 and -4.
Sorry I'm not sure what you mean by "symbolic answer."
*If you don't see how to factor this trinomial, you can still apply the quadratic formula to get the same answer without being "clever."
