Observe the graph:

The compound inequality from the graph solution set is $\"\"$ .

Determine factor that can be added or subtracted from each term so that it is in the form $\"\"$ or $\"\"$ .

This implies that $\"\"$ .

Solve the solution sets.

Case(i)

$\"\"$ (First solution)

$\"\"$ (Subtract $\"\"$ from each side)

$\"\"$ (Add: $\"\"$ )

Case(ii)

$\"\"$ (Second solution)

$\"\"$ (Subtract $\"\"$ from each side)

$\"\"$ (Subtract: $\"\"$ )

This implies that $\"\"$ .

$\"\"$

The inequality is $\"\"$ .
