$\"\"$

The inequality is $\"\"$ .

Solve inequality.

$\"\"$ (Original inequality)

$\"\"$ (Multiply each side by $\"\"$ )

$\"\"$ (Cancel common terms)

$\"\"$ (Multiply each side by negative one and flip the symbol)

$\"\"$ (Multiply)

Therefore,the solution set is $\"\"$ .

$\"\"$

Check:

Case(i): $\"\"$

$\"\"$ (Original inequality)

$\"\"$ (Substitute $\"\"$ )

$\"\"$ (Simplify)

Hence the value of $\"\"$ is satisfied.
