Solve (x - 1) (x 1) < 0

Question

Solve the inequality

Solve the inequality by testing the values in the interval

Solve the inequality by separating into cases

Solve for x

0 < x < 1

Alternative Form

x \in (0, 1)

Evaluate

(x - 1) (x \times 1) < 0

Remove the parentheses

(x - 1) x \times 1 < 0

Multiply the terms

More Steps

x (x - 1) < 0

Rewrite the expression

x (x - 1) = 0

Separate the equation into 2 possible cases

x = 0 x - 1 = 0

Solve the equation

More Steps

x = 0 x = 1

Determine the test intervals using the critical values

x < 0 0 < x < 1 x > 1

Choose a value form each interval

x_{1} = - 1 x_{2} = \frac{1}{2} x_{3} = 2

To determine if x < 0 is the solution to the inequality,test if the chosen value x = - 1 satisfies the initial inequality

More Steps

x < 0 is not a solution x_{2} = \frac{1}{2} x_{3} = 2

To determine if 0 < x < 1 is the solution to the inequality,test if the chosen value x = \frac{1}{2} satisfies the initial inequality

More Steps

x < 0 is not a solution 0 < x < 1 is the solution x_{3} = 2

To determine if x > 1 is the solution to the inequality,test if the chosen value x = 2 satisfies the initial inequality

More Steps

x < 0 is not a solution 0 < x < 1 is the solution x > 1 is not a solution

Solution

0 < x < 1

Alternative Form

x \in (0, 1)
