(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

i know this seems basic, but read my attempt at solution.

x^2 -4>0

3. The attempt at a solution

i moved 4 over and took the square root of both sides to make the it x>(+)or(-)2

but that is not the answer, that is the error and we have to prove why it is the error. Any ideas here?
