Solution for h(x)=-4x(x^2-1)(x-7) equation: 


Simplifying
h(x) = -4x(x2 + -1)(x + -7)

Multiply h * x
hx = -4x(x2 + -1)(x + -7)

Reorder the terms:
hx = -4x(-1 + x2)(x + -7)

Reorder the terms:
hx = -4x(-1 + x2)(-7 + x)

Multiply (-1 + x2) * (-7 + x)
hx = -4x(-1(-7 + x) + x2(-7 + x))
hx = -4x((-7 * -1 + x * -1) + x2(-7 + x))
hx = -4x((7 + -1x) + x2(-7 + x))
hx = -4x(7 + -1x + (-7 * x2 + x * x2))
hx = -4x(7 + -1x + (-7x2 + x3))
hx = -4x(7 + -1x + -7x2 + x3)
hx = (7 * -4x + -1x * -4x + -7x2 * -4x + x3 * -4x)
hx = (-28x + 4x2 + 28x3 + -4x4)

Solving
hx = -28x + 4x2 + 28x3 + -4x4

Solving for variable 'h'.

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

Divide each side by 'x'.
h = -28 + 4x + 28x2 + -4x3

Simplifying
h = -28 + 4x + 28x2 + -4x3
