$(-\infty,-2)$

Step 1. Identify boundary points (zeros) as $x=-2,5$ which divide the x-axis into three intervals $(-\infty,-2),(-2,5),(5,\infty)$ Step 2. Choose test values in each interval $x=-3,0,6$ and test the inequality to get $True,\ False, \ False$ Step 3. Thus the solution interval is $(-\infty,-2)$
