Answer:
x=3\\x=-2


Explanation:

1. You have the following expression:


(x^(2)+8x+4)/(x^(2)-x-6)

3. The denominatoir cannot be zero, so, you must find its roots:


x^(2)-x-6=0

Factorizing it, you obtain:


(x-3)(x+2)=0\\x=3\\x=-2

Then:


(x^(2)+8x+4)/((x-3)(x+2))

4. Therefore, the values that are discontinuity of
(x^(2)+8x+4)/(x^(2)-x-6) are:


x=3\\x=-2
