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


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

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

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

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

Combine like terms: 1x + -4x = -3x
0 = (-4 + -3x + x2)(3 + -2x)

Multiply (-4 + -3x + x2) * (3 + -2x)
0 = (-4(3 + -2x) + -3x * (3 + -2x) + x2(3 + -2x))
0 = ((3 * -4 + -2x * -4) + -3x * (3 + -2x) + x2(3 + -2x))
0 = ((-12 + 8x) + -3x * (3 + -2x) + x2(3 + -2x))
0 = (-12 + 8x + (3 * -3x + -2x * -3x) + x2(3 + -2x))
0 = (-12 + 8x + (-9x + 6x2) + x2(3 + -2x))
0 = (-12 + 8x + -9x + 6x2 + (3 * x2 + -2x * x2))
0 = (-12 + 8x + -9x + 6x2 + (3x2 + -2x3))

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

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

Solving
0 = -12 + -1x + 9x2 + -2x3

Solving for variable 'x'.

Combine like terms: 0 + 12 = 12
12 + x + -9x2 + 2x3 = -12 + -1x + 9x2 + -2x3 + 12 + x + -9x2 + 2x3

Reorder the terms:
12 + x + -9x2 + 2x3 = -12 + 12 + -1x + x + 9x2 + -9x2 + -2x3 + 2x3

Combine like terms: -12 + 12 = 0
12 + x + -9x2 + 2x3 = 0 + -1x + x + 9x2 + -9x2 + -2x3 + 2x3
12 + x + -9x2 + 2x3 = -1x + x + 9x2 + -9x2 + -2x3 + 2x3

Combine like terms: -1x + x = 0
12 + x + -9x2 + 2x3 = 0 + 9x2 + -9x2 + -2x3 + 2x3
12 + x + -9x2 + 2x3 = 9x2 + -9x2 + -2x3 + 2x3

Combine like terms: 9x2 + -9x2 = 0
12 + x + -9x2 + 2x3 = 0 + -2x3 + 2x3
12 + x + -9x2 + 2x3 = -2x3 + 2x3

Combine like terms: -2x3 + 2x3 = 0
12 + x + -9x2 + 2x3 = 0
