x+2
_____________ x = -2
therefore, the solution for your equation is
x = -2

you cannot use -4 and +4 because it will turn your denominator into zero. And a fraction with a zero denominator is undefined or has no solution.

hahaha! even -2 won't do... positive 2 will.
your solution set SHOULD NOT include 4, -4, -2 amd +2.
you cannot also use a positive number larger than 4 because the answer of your equation will be positive, and therefore will not be

x+2
-------------- 0
then case (a) = x x belongs to (-infinity, -4) and (4, infinity)
Hence in Case I with cases(a)&(b) x values are (-infinity , -2)
Case II
x+2 0 and (x+4)(x-4) -2 and
case(b) x belongs to (-4,4)
Hence in Case II with cases(a)&(b) x values are (-2, 4)
Totally the solution for X values is
(-infinity, -2) and (-2, 4)
in this x never takes a value of -2 and 4
In words X takes all the values less than 4 but not -2.

x can take all values from -2 to 4 except the end values. It's real simple try it out ! :)
