$\"\"$

\

The inequality is $\"\"$ .

\

$\"\"$ is non negative.

\

Consider $\"\"$ .

\

$\"\"$

\

Since $\"\"$ .

\

$\"\"$ .

\

$\"\"$

\

Let $\"\"$ .

\

$\"\"$ is positive for all values of $\"\"$ .

\

Consider $\"\"$ .

\

$\"\"$

\

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

\

$\"\"$

\

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

\

Draw a sign chart by using the values $\"\"$ and $\"\"$ .

\

$\"\"$

\

Note : The hallow circle denote that the value are excluded in the solution set.

\

Observe the sign chart :

\

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

\

The zero at $\"\"$ is the location of sign change because it has multiplicity $\"\"$ .

\

\

The zero at $\"\"$ is not the location of sign change because it has multiplicity $\"\"$ .

\

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

\

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

\

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

\

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

\

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

\

The solutions of $\"\"$ are $\"\"$ values such that $\"\"$ is positive.

\

From the sign chart the solution is $\"\"$ .

\

From the sign chart,the solution set is $\"\"$ .

\

$\"\"$

\

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