30x5−12x4=0
Factor the expression
6x4(5x−2)=0
Divide both sides
x4(5x−2)=0
Separate the equation into 2 possible cases
x4=05x−2=0
The only way a power can be 0 is when the base equals 0
x=05x−2=0
Solve the equation
More Steps

Evaluate
5x−2=0
Move the constant to the right-hand side and change its sign
5x=0+2
Removing 0 doesn't change the value,so remove it from the expression
5x=2
Divide both sides
55x=52
Divide the numbers
x=52
x=0x=52
Solution
x1=0,x2=52
