If |x+2|=4, what is the value of x ?
x=2, x=-6

(1) x^2 is different from 4
x^2 is different from 4
(The wording is a bit ambiguous, but I take it to mean that x^2 DOESN'T EQUAL 4)
we have two values for x, x=-6 and x=2.
When x=2, then x^2 = 4 which is invalid.
When x=-6 then x^2 = 36 which is valid.
x=6
SUFFICIENT

(2) x^2 = 36
x=-6, x=6
(plug both x values into the stem)
|x+2|=4
|-6+2|=4
|-4|=4
4=4 VALID
|x+2|=4
|6+2|=4
|8|=4
8=4 INVALID

There is only one valid answer for #2.
SUFFICIENT

(D)
