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


Simplifying
h(x) = x(x + -1)(x + 2)(x + -4)

Multiply h * x
hx = x(x + -1)(x + 2)(x + -4)

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

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

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

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

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

Multiply (-2 + 1x + x2) * (-4 + x)
hx = x(-2(-4 + x) + 1x * (-4 + x) + x2(-4 + x))
hx = x((-4 * -2 + x * -2) + 1x * (-4 + x) + x2(-4 + x))
hx = x((8 + -2x) + 1x * (-4 + x) + x2(-4 + x))
hx = x(8 + -2x + (-4 * 1x + x * 1x) + x2(-4 + x))
hx = x(8 + -2x + (-4x + 1x2) + x2(-4 + x))
hx = x(8 + -2x + -4x + 1x2 + (-4 * x2 + x * x2))
hx = x(8 + -2x + -4x + 1x2 + (-4x2 + x3))

Combine like terms: -2x + -4x = -6x
hx = x(8 + -6x + 1x2 + -4x2 + x3)

Combine like terms: 1x2 + -4x2 = -3x2
hx = x(8 + -6x + -3x2 + x3)
hx = (8 * x + -6x * x + -3x2 * x + x3 * x)
hx = (8x + -6x2 + -3x3 + x4)

Solving
hx = 8x + -6x2 + -3x3 + x4

Solving for variable 'h'.

Move all terms containing h to the left, all other terms to the right.

Divide each side by 'x'.
h = 8 + -6x + -3x2 + x3

Simplifying
h = 8 + -6x + -3x2 + x3
