If you have an equality of the form...

$(x+a)\cdot(x-b)\ge0$

The inequality can be writen as...

$a\leq x\leq b$

I'll show you how it looks like on the graph

the graph indicates that x is any value less than or equal to -6 or greater than or equal to 3, which is the red area

$\begin{gathered} x\leq-6 \\ x\ge3 \end{gathered}$
