Question
Solve the inequality
Solve the inequality by testing the values in the interval
Solve the inequality by separating into cases
0<x<3
Alternative Form
x∈(0,3)
Evaluate
x2(3−x)(x×1)>0
Remove the parentheses
x2(3−x)x×1>0
Multiply the terms
More Steps

Evaluate
x2(3−x)x×1
Rewrite the expression
x2(3−x)x
Multiply the terms with the same base by adding their exponents
x2+1(3−x)
Add the numbers
x3(3−x)
x3(3−x)>0
Rewrite the expression
x3(3−x)=0
Separate the equation into 2 possible cases
x3=03−x=0
The only way a power can be 0 is when the base equals 0
x=03−x=0
Solve the equation
More Steps

Evaluate
3−x=0
Move the constant to the right-hand side and change its sign
−x=0−3
Removing 0 doesn't change the value,so remove it from the expression
−x=−3
Change the signs on both sides of the equation
x=3
x=0x=3
Determine the test intervals using the critical values
x<00<x<3x>3
Choose a value form each interval
x1=−1x2=2x3=4
To determine if x<0 is the solution to the inequality,test if the chosen value x=−1 satisfies the initial inequality
