Step-by-step explanation:
The first, we will write our inequality in another form:



We want to know when is it equal to 0.
First we solve the equation
:




So we want to know when
is true. We know, when a>0 function is negative when x is between two zeros. In our example a=3>0. Then we have:
It is true if

I'm 90% sure that's right, sorry if I'm wrong :/
