2x6(12x3−7)=0
Elimination the left coefficient
x6(12x3−7)=0
Separate the equation into 2 possible cases
x6=012x3−7=0
The only way a power can be 0 is when the base equals 0
x=012x3−7=0
Solve the equation
More Steps

Evaluate
12x3−7=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
Divide both sides
1212x3=127
Divide the numbers
x3=127
Take the 3-th root on both sides of the equation
3x3=3127
