The inequality is .

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

The exclude value of the inequality is 0.

Solve the related equation

Solutions of the related equation are .

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

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

Test interval   x - value                        Inequality                                             Conclusion

                                              True

                    False

                           True

                                                                 False

The above conclude that the inequality is satisfied for all x - values in and .

Solution of the inequality is .
