GPT 3.5
The expression 12 / (x^2-4) will have a non-permissible value if the denominator becomes zero.
To find the non-permissible value, we need to solve the equation x^2 - 4 = 0.
x^2 - 4 = 0 can be factored as (x - 2)(x + 2) = 0.
Setting each factor equal to zero:
x - 2 = 0 -> x = 2
x + 2 = 0 -> x = -2
So the non-permissible values for the expression 12 / (x^2 - 4) are x = 2 and x = -2.
