Answer:
-5 < x < 5
Step-by-step explanation:
|x| < 5
This can be split into two cases: x < 5 and -x < 5 because |x| could be either x or -x depending on whether x is positive, negative, or 0. Solving the second one we get x > -5 so the answer is -5 < x < 5.

If you would like to solve the inequality 4 * (x + 2)^2 < 0, you can do this using the following steps:
4 * (x + 2)^2 < 0
4 * (x^2 + 4x + 4) < 0 /4
x^2 + 4x + 4 < 0
no solutions
The correct result would be: There are no solutions.
