$\"\"$

The inequality algebraically function is $\"\"$ .

Step 1: Write the inequality so that a rational expression $\"\"$ is on the left side and zero is on the right side.

$\"\"$ .

Step 2: Determine the real zeros ( $\"\"$ -intercepts of the graph )of $\"\"$ and the real numbers for which $\"\"$ is undefined.

The zeroes of the function are the values of $\"\"$ for which $\"\"$ .

The zeroes of $\"\"$ is $\"\"$ or $\"\"$ and $\"\"$ .

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

$\"\"$

Step 3: Use the zeros and undefined values found in Step 2 to divide the real number line into intervals.

The function is defined for all values of $\"\"$ except at $\"\"$ or $\"\"$ and $\"\"$ .

The function intervals are $\"\"$ .

$\"\"$

Step 4: Select a number in each interval, evaluate $\"\"$ at the number, and determine whether $\"\"$ is positive or negative.

If $\"\"$ is positive, all values of $\"\"$ in the interval are positive. If $\"\"$ is negative, all values of $\"\"$ in the interval are negative.

$\"\"$

The real zero of numerator is $\"\"$ , $\"\"$ and $\"\"$ .

So the real zeros are divide the $\"\"$ - axis into four intervals.

Choosing a number for $\"\"$ in each interval and evaluating $\"\"$ .
