Solution for 1120=(x+4)*(x-2)*x equation: 


Simplifying
1120 = (x + 4)(x + -2) * x

Reorder the terms:
1120 = (4 + x)(x + -2) * x

Reorder the terms:
1120 = (4 + x)(-2 + x) * x

Reorder the terms for easier multiplication:
1120 = x(4 + x)(-2 + x)

Multiply (4 + x) * (-2 + x)
1120 = x(4(-2 + x) + x(-2 + x))
1120 = x((-2 * 4 + x * 4) + x(-2 + x))
1120 = x((-8 + 4x) + x(-2 + x))
1120 = x(-8 + 4x + (-2 * x + x * x))
1120 = x(-8 + 4x + (-2x + x2))

Combine like terms: 4x + -2x = 2x
1120 = x(-8 + 2x + x2)
1120 = (-8 * x + 2x * x + x2 * x)
1120 = (-8x + 2x2 + x3)

Solving
1120 = -8x + 2x2 + x3

Solving for variable 'x'.

Reorder the terms:
1120 + 8x + -2x2 + -1x3 = -8x + 8x + 2x2 + -2x2 + x3 + -1x3
