x can not equal 12 or 12
since fractions can't have 0 in the bottom just look for a number that makes the bottom equal 0 and thats what the variable can't equal

Since its division, the domain cannot be a number that makes the denominator equal to zero.
to find out what "X" cannot be, we must remove the square(the second power above the X) after setting the equation to zero.
x^2  144 = 0
isolate the variable "X" from the number (move on of them over)
x^2 = 144
since the exponent is "2", we will square root each side. ( if it were 3, we third root, and so on, so forth)
square root of x^2 = x
square root of 144 = 12
so X=12
the domain (X) cannot equal 12 , so your answer would be:
(infinity,12)U(12,infinity)
everything below 12 and every thing above 12
