The inequality is $\"\"$ .

Simplify the inequality.

Now, there are two ways this product could be greater zero.Two factors must be positive or negitive.

Case 1 :

$\"\"$ and $\"\"$ .

The solution in interval notation is $\"\"$ .

The solution set is $\"\"$ .

Case 2 :

$\"\"$ and $\"\"$ .

The solution in interval notation is $\"\"$ .

The solution set is $\"\"$ .

Thus, the solution of in equality is $\"\"$ .
