Observe the graph, the graph containing two lines, one line starts from $\"\"$ to negative infinity but $\"\"$ not including in the solution set since it is contain circle.

The remaining line starts from $\"\"$ to positive infinity and here $\"\"$ is not including in the solution set since it contain circle.

The graph shows the solution $\"\"$ . $\"\"$

The compound inequality is $\"\"$ .
