Answer
$(-\infty,-2]U(1,3]$
Work Step by Step
Step 1. Identify boundary points (zeros and asymptotes) as $x=-2,1,3$ which divide the x-axis into four intervals $(-\infty,-2],[-2,1),(1,3],[3,\infty)$
Step 2. Choose test values in each interval $x=-3,0,2,4$ and test the inequality to get $True,\ False,\ True,\ False$
Step 3. Thus the solution intervals are $(-\infty,-2]U(1,3]$
