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