Solve the Inequality for x x^2-x<0

$x^{2} - x < 0$

Convert the inequality to an equation.

$x^{2} - x = 0$

Factor $x$ out of $x^{2} - x$ .

Factor $x$ out of $x^{2}$ .

$x \cdot x - x = 0$

Factor $x$ out of $- x$ .

$x \cdot x + x \cdot - 1 = 0$

Factor $x$ out of $x \cdot x + x \cdot - 1$ .

$x (x - 1) = 0$

If any individual factor on the left side of the equation is equal to $0$ , the entire expression will be equal to $0$ .

$x = 0$

$x - 1 = 0$

Set $x$ equal to $0$ .

$x = 0$

Set $x - 1$ equal to $0$ and solve for $x$ .

Set $x - 1$ equal to $0$ .

$x - 1 = 0$

Add $1$ to both sides of the equation.

$x = 1$

The final solution is all the values that make $x (x - 1) = 0$ true.

$x = 0, 1$

Use each root to create test intervals.

$x < 0$

$0 < x < 1$

$x > 1$

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 $x < 0$ to see if it makes the inequality true.

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.

${(- 2)}^{2} - (- 2) < 0$

The left side $6$ is not less than the right side $0$ , which means that the given statement is false.

False

Test a value on the interval $0 < x < 1$ to see if it makes the inequality true.

Choose a value on the interval $0 < x < 1$ and see if this value makes the original inequality true.

$x = 0.5$

Replace $x$ with $0.5$ in the original inequality.

${(0.5)}^{2} - (0.5) < 0$

The left side $- 0.25$ is less than the right side $0$ , which means that the given statement is always true.

True

Test a value on the interval $x > 1$ to see if it makes the inequality true.

Choose a value on the interval $x > 1$ and see if this value makes the original inequality true.

$x = 4$

Replace $x$ with $4$ in the original inequality.

${(4)}^{2} - (4) < 0$

The left side $12$ is not less than the right side $0$ , which means that the given statement is false.

False

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

$x < 0$ False

$0 < x < 1$ True

$x > 1$ False

$x < 0$ False

$0 < x < 1$ True

$x > 1$ False

The solution consists of all of the true intervals.

$0 < x < 1$

The result can be shown in multiple forms.

Inequality Form:

$0 < x < 1$

Interval Notation:

$(0, 1)$
