$\"\"$

\

The inequality is $\"\"$ .

\

Let $\"\"$ .

\

Consider only the real zeros.

\

$\"\"$ has real zeros at $\"\"$ , $\"\"$ , $\"\"$ and $\"\"$ .

\

Therefore $\"\"$ has $\"\"$ real zeros at $\"\"$ and $\"\"$ .

\

\

Create a sign chart using the values $\"\"$ and $\"\"$ .

\

$\"\"$

\

\

Note : The solid circle denote that the value are included in the solution set.

\

Observe the sign chart :

\

The set of value of $\"\"$ denoted in pink color represents the solution set.

\

Determine whether $\"\"$ is positive or negative on the test intervals.

\

$\"\"$

\

Test intervals are $\"\"$ and $\"\"$ .

\

Subustiute the values in the inequality $\"\"$ .

\

If $\"\"$ then $\"\"$ .

\

If $\"\"$ then $\"\"$ .

\

If $\"\"$ then $\"\"$ .

\

If $\"\"$ then $\"\"$ .

\

If $\"\"$ then $\"\"$ .

\

The solutions of $\"\"$ are $\"\"$ values for which $\"\"$ is negitive or

\

equal to $\"\"$ .

\

The solution set is $\"\"$ .

\

$\"\"$

\

The solution set of $\"\"$ is $\"\"$ .
