Solution for 40=x(x-2)(x-1) equation: 


Simplifying
40 = x(x + -2)(x + -1)

Reorder the terms:
40 = x(-2 + x)(x + -1)

Reorder the terms:
40 = x(-2 + x)(-1 + x)

Multiply (-2 + x) * (-1 + x)
40 = x(-2(-1 + x) + x(-1 + x))
40 = x((-1 * -2 + x * -2) + x(-1 + x))
40 = x((2 + -2x) + x(-1 + x))
40 = x(2 + -2x + (-1 * x + x * x))
40 = x(2 + -2x + (-1x + x2))

Combine like terms: -2x + -1x = -3x
40 = x(2 + -3x + x2)
40 = (2 * x + -3x * x + x2 * x)
40 = (2x + -3x2 + x3)

Solving
40 = 2x + -3x2 + x3

Solving for variable 'x'.

Reorder the terms:
40 + -2x + 3x2 + -1x3 = 2x + -2x + -3x2 + 3x2 + x3 + -1x3

Combine like terms: 2x + -2x = 0
40 + -2x + 3x2 + -1x3 = 0 + -3x2 + 3x2 + x3 + -1x3
40 + -2x + 3x2 + -1x3 = -3x2 + 3x2 + x3 + -1x3

Combine like terms: -3x2 + 3x2 = 0
40 + -2x + 3x2 + -1x3 = 0 + x3 + -1x3
40 + -2x + 3x2 + -1x3 = x3 + -1x3

Combine like terms: x3 + -1x3 = 0
40 + -2x + 3x2 + -1x3 = 0
