Using the property that anything over 0 is undefined, we can set x+2 to 0 and solve it to find the undefined points.
[tex]x+2 = 0[/tex]
[tex]x = -2[/tex]
So when x is -2, the equation will be undefined because of the rules about division by zero.

When setting the factored denominator to 0, you get that x+2=0, x=-2. So, x cannot be -2.
