How do you see if the following inequality holds true for (-2,0)?(adsbygoogle = window.adsbygoogle || []).push({});

(-x/4)*(x+2)>1

For that matter how do you test inequalities for a given interval in general?

Certainly there must be a way other than to check all values of (-x/4)*(x+2) in (-2,0) and see if they are greater than 1?
