First step: Factor the expression.
(x + 8) / (x - 6)(x + 4)
Set each factor of the denominator equal to zero.
x - 6 = 0                                        x + 4 = 0
add 6 to both sides                      subtract 4 from both sides
x = 6                                             x = -4
The function would be undefined if x = 6 or x = -4
