Solution for f(x)=(x*x-1)(x-2) equation:


Simplifying
f(x) = (x * x + -1)(x + -2)

Multiply f * x
fx = (x * x + -1)(x + -2)

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

Reorder the terms:
fx = (-1 + x2)(x + -2)

Reorder the terms:
fx = (-1 + x2)(-2 + x)

Multiply (-1 + x2) * (-2 + x)
fx = (-1(-2 + x) + x2(-2 + x))
fx = ((-2 * -1 + x * -1) + x2(-2 + x))
fx = ((2 + -1x) + x2(-2 + x))
fx = (2 + -1x + (-2 * x2 + x * x2))
fx = (2 + -1x + (-2x2 + x3))
fx = (2 + -1x + -2x2 + x3)

Solving
fx = 2 + -1x + -2x2 + x3

Solving for variable 'f'.

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

Divide each side by 'x'.
f = 2x-1 + -1 + -2x + x2
