Answer
$(-1,\infty)$
Work Step by Step
Step 1.Factor and identify boundary points (zeros) $(x+1)(x^2-x+1)\gt0$ as $x=-1$ which divide the x-axis into two intervals $(-\infty,-1),(-1,\infty)$
Step 2. Choose test values in each interval $x=-2,0$ and test the inequality to get $False,\ True$
Step 3. Thus the solution interval is $(-1,\infty)$
