Solution for f(x)=-5x(x^2-36x)(x-2) equation: 


Simplifying
f(x) = -5x(x2 + -36x)(x + -2)

Multiply f * x
fx = -5x(x2 + -36x)(x + -2)

Reorder the terms:
fx = -5x(-36x + x2)(x + -2)

Reorder the terms:
fx = -5x(-36x + x2)(-2 + x)

Multiply (-36x + x2) * (-2 + x)
fx = -5x(-36x * (-2 + x) + x2(-2 + x))
fx = -5x((-2 * -36x + x * -36x) + x2(-2 + x))
fx = -5x((72x + -36x2) + x2(-2 + x))
fx = -5x(72x + -36x2 + (-2 * x2 + x * x2))
fx = -5x(72x + -36x2 + (-2x2 + x3))

Combine like terms: -36x2 + -2x2 = -38x2
fx = -5x(72x + -38x2 + x3)
fx = (72x * -5x + -38x2 * -5x + x3 * -5x)
fx = (-360x2 + 190x3 + -5x4)

Solving
fx = -360x2 + 190x3 + -5x4

Solving for variable 'f'.

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

Divide each side by 'x'.
f = -360x + 190x2 + -5x3

Simplifying
f = -360x + 190x2 + -5x3
