The inequality is $\"\"$ .

Draw a coordinate plane.

Graph the function $\"\"$ on the interval $\"\"$ .

$\"\"$

Observe the graph :

The zeros of $\"\"$ are about $\"\"$ and $\"\"$ .

The graph of $\"\"$ is below the other graph $\"\"$ when $\"\"$ or $\"\"$ .

Therefore, $\"\"$ on $\"\"$ or $\"\"$ . $\"\"$

The solution set is $\"\"$ .
