x+2>0 x-2<0
For the product to be negative, x+2 and x-2 have to be of the opposite signs. Consider the case when x+2 is positive and x-2 is negative.
x\in \left(-2,2\right)
The solution satisfying both inequalities is x\in \left(-2,2\right).
x-2>0 x+2<0
Consider the case when x-2 is positive and x+2 is negative.
x\in \emptyset
This is false for any x.
x\in \left(-2,2\right)
The final solution is the union of the obtained solutions.
