Solution for 0=3x(4x-1)(x-2) equation: 


Simplifying
0 = 3x(4x + -1)(x + -2)

Reorder the terms:
0 = 3x(-1 + 4x)(x + -2)

Reorder the terms:
0 = 3x(-1 + 4x)(-2 + x)

Multiply (-1 + 4x) * (-2 + x)
0 = 3x(-1(-2 + x) + 4x * (-2 + x))
0 = 3x((-2 * -1 + x * -1) + 4x * (-2 + x))
0 = 3x((2 + -1x) + 4x * (-2 + x))
0 = 3x(2 + -1x + (-2 * 4x + x * 4x))
0 = 3x(2 + -1x + (-8x + 4x2))

Combine like terms: -1x + -8x = -9x
0 = 3x(2 + -9x + 4x2)
0 = (2 * 3x + -9x * 3x + 4x2 * 3x)
0 = (6x + -27x2 + 12x3)

Solving
0 = 6x + -27x2 + 12x3

Solving for variable 'x'.
Remove the zero:
-6x + 27x2 + -12x3 = 6x + -27x2 + 12x3 + -6x + 27x2 + -12x3

Reorder the terms:
-6x + 27x2 + -12x3 = 6x + -6x + -27x2 + 27x2 + 12x3 + -12x3

Combine like terms: 6x + -6x = 0
-6x + 27x2 + -12x3 = 0 + -27x2 + 27x2 + 12x3 + -12x3
-6x + 27x2 + -12x3 = -27x2 + 27x2 + 12x3 + -12x3

Combine like terms: -27x2 + 27x2 = 0
-6x + 27x2 + -12x3 = 0 + 12x3 + -12x3
-6x + 27x2 + -12x3 = 12x3 + -12x3

Combine like terms: 12x3 + -12x3 = 0
-6x + 27x2 + -12x3 = 0

Factor out the Greatest Common Factor (GCF), '3x'.
