Question
Solve the equation
x1=0,x2=21
Alternative Form
x1=0,x2=0.5
Evaluate
x2−8x5=0
Factor the expression
x2(1−8x3)=0
Separate the equation into 2 possible cases
x2=01−8x3=0
The only way a power can be 0 is when the base equals 0
x=01−8x3=0
Solve the equation
More Steps

Evaluate
1−8x3=0
Move the constant to the right-hand side and change its sign
−8x3=0−1
Removing 0 doesn't change the value,so remove it from the expression
−8x3=−1
Change the signs on both sides of the equation
8x3=1
Divide both sides
88x3=81
Divide the numbers
x3=81
Take the 3-th root on both sides of the equation
3x3=381
