$(- \infty, 0) \cup (0, \infty)$

Use each root to create test intervals.

$x < - \frac{1}{2}$

$- \frac{1}{2} < x < 0$

$x > 0$

Choose a test value from each interval and plug this value into the original inequality to determine which intervals satisfy the inequality.

Test a value on the interval $x < - \frac{1}{2}$ to see if it makes the inequality true.

Choose a value on the interval $x < - \frac{1}{2}$ and see if this value makes the original inequality true.

$x = - 3$

Replace $x$ with $- 3$ in the original inequality.

$\frac{- 3}{- 3 \cdot - 3} - \frac{3}{3} \geq - 3$

The left side $- 1.\overline{3}$ is greater than the right side $- 3$ , which means that the given statement is always true.

True

Test a value on the interval $- \frac{1}{2} < x < 0$ to see if it makes the inequality true.

Choose a value on the interval $- \frac{1}{2} < x < 0$ and see if this value makes the original inequality true.

$x = - 0.25$

Replace $x$ with $- 0.25$ in the original inequality.

$\frac{- 3}{- 3 \cdot - 0.25} - \frac{3}{3} \geq - 3$

The left side $- 5$ is less than the right side $- 3$ , which means that the given statement is false.

False

Choose a value on the interval $x > 0$ and see if this value makes the original inequality true.

$x = 2$

Replace $x$ with $2$ in the original inequality.

$\frac{- 3}{- 3 \cdot 2} - \frac{3}{3} \geq - 3$

The left side $- 0.5$ is greater than the right side $- 3$ , which means that the given statement is always true.

True

Compare the intervals to determine which ones satisfy the original inequality.

$x < - \frac{1}{2}$ True

$- \frac{1}{2} < x < 0$ False

$x > 0$ True

$x < - \frac{1}{2}$ True
