You can put this solution on YOUR website!
what is the domain of x+20/x^2-144?
-----------------------
That denominator cannot be zero.
So x^2-144 cannot be 0
(x-12)(x+12) cannot be 0
x cannot be 12 and x cannot be -12
----------------------------------------
Domain: All Real Numbers excetp x = -12 and x = +12
