Solve 8x-x^2>0 - ScanMath

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 < 8

Alternative Form

x \in (0, 8)

Evaluate

8 x - x^{2} > 0

Rewrite the expression

8 x - x^{2} = 0

Factor the expression

More Steps

x (8 - x) = 0

When the product of factors equals 0,at least one factor is 0

x = 0 8 - x = 0

Solve the equation for x

More Steps

x = 0 x = 8

Determine the test intervals using the critical values

x < 0 0 < x < 8 x > 8

Choose a value form each interval

x_{1} = - 1 x_{2} = 4 x_{3} = 9

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} = 4 x_{3} = 9

To determine if 0 < x < 8 is the solution to the inequality,test if the chosen value x = 4 satisfies the initial inequality

More Steps

x < 0 is not a solution 0 < x < 8 is the solution x_{3} = 9

To determine if x > 8 is the solution to the inequality,test if the chosen value x = 9 satisfies the initial inequality

More Steps

x < 0 is not a solution 0 < x < 8 is the solution x > 8 is not a solution

Solution

0 < x < 8

Alternative Form

x \in (0, 8)
