Answer
$(-\infty,-4)U(1,\infty) $
Work Step by Step
Step 1. Based on the given inequality, identify the boundary points $x=-4,1$ and possible intervals $(-\infty,-4),(-4,1),(1,\infty)$
Step 2 choose test values $x=-5,0,2$, test the inequality and get results $True,\ False,\ True$
Step 3. Obtain solutions $(-\infty,-4)U(1,\infty) $
