$\"\"$

\

The inequality is $\"\"$ .

\

$\"\"$ is non negative.

\

Consider $\"\"$ .

\

$\"\"$ is in the form of $\"\"$ .

\

$\"\"$ .

\

Therefore $\"\"$ .

\

$\"\"$

\

$\"\"$

\

Let $\"\"$ .

\

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

\

$\"\"$

\

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

\

Draw a sign chart by 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 blue color represents the solution set.

\

Because the zeros at $\"\"$ and $\"\"$ has multiplicity $\"\"$ there is no location of sign change.

\

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

\

From the sign chart the solution is set of all real numbers.

\

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

\

$\"\"$

\

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