You are correct, but I would remove the x and answer it with them connected. It looks like you want the x to be distributed, which would be wrong.

It should look more like:

$20(n+1)(n-1)$

$-|x| > 4\ \ \ \ \ |\text{change the signs}\\\\|x| < -4\ FALSE!!!!$

We know |x| ≥ 0 for all real numbers. Therefore your answer is x ∈ ∅ (no solution).
