Step 1 :

The rational inequality is .

State the exclude values, those are the values for which the denominator is zero.

The exclude value of the inequality is 3.

Step 2 :

Solve the related equation .

Solution of related equation .

Step 3 :

Draw the vertical lines at the exclude values and at the solution to separate the number line into intervals.

Step 4 :

Now test sample values in each interval to determine whether the values in the interval satisfy the inequality.

Test interval image- value Inequality   Conclusion
image image image True
image image image False
image image image True

Step 5 :

Since the original inequality contains a "image" symbol, exclude it into set of solutions at image.

Since the above statement is true, image is a solution of inequality.

Conclude that the inequality is satisfied for all image- values in image and image.

Solution of the inequality is image.

Solution :

Solution of the inequality is image.
