Question
Solve the equation
x1=0,x2=63126
Alternative Form
x1=0,x2≈0.83555
Evaluate
7x2−12x5=0
Factor the expression
x2(7−12x3)=0
Separate the equation into 2 possible cases
x2=07−12x3=0
The only way a power can be 0 is when the base equals 0
x=07−12x3=0
Solve the equation
More Steps

Evaluate
7−12x3=0
Move the constant to the right-hand side and change its sign
−12x3=0−7
Removing 0 doesn't change the value,so remove it from the expression
−12x3=−7
Change the signs on both sides of the equation
12x3=7
Divide both sides
1212x3=127
Divide the numbers
x3=127
Take the 3-th root on both sides of the equation
3x3=3127
