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


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

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

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

Multiply (-1 + 3x) * (3 + 4x)
0 = -2x(-1(3 + 4x) + 3x * (3 + 4x))
0 = -2x((3 * -1 + 4x * -1) + 3x * (3 + 4x))
0 = -2x((-3 + -4x) + 3x * (3 + 4x))
0 = -2x(-3 + -4x + (3 * 3x + 4x * 3x))
0 = -2x(-3 + -4x + (9x + 12x2))

Combine like terms: -4x + 9x = 5x
0 = -2x(-3 + 5x + 12x2)
0 = (-3 * -2x + 5x * -2x + 12x2 * -2x)
0 = (6x + -10x2 + -24x3)

Solving
0 = 6x + -10x2 + -24x3

Solving for variable 'x'.
Remove the zero:
-6x + 10x2 + 24x3 = 6x + -10x2 + -24x3 + -6x + 10x2 + 24x3

Reorder the terms:
-6x + 10x2 + 24x3 = 6x + -6x + -10x2 + 10x2 + -24x3 + 24x3

Combine like terms: 6x + -6x = 0
-6x + 10x2 + 24x3 = 0 + -10x2 + 10x2 + -24x3 + 24x3
-6x + 10x2 + 24x3 = -10x2 + 10x2 + -24x3 + 24x3

Combine like terms: -10x2 + 10x2 = 0
-6x + 10x2 + 24x3 = 0 + -24x3 + 24x3
-6x + 10x2 + 24x3 = -24x3 + 24x3

Combine like terms: -24x3 + 24x3 = 0
-6x + 10x2 + 24x3 = 0
