Simplifying
f(x) = x2 + 8x + -3

Multiply f * x
fx = x2 + 8x + -3

Reorder the terms:
fx = -3 + 8x + x2

Solving
fx = -3 + 8x + x2

Solving for variable 'f'.

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

Divide each side by 'x'.
f = -3x-1 + 8 + x

Simplifying
f = -3x-1 + 8 + x

Reorder the terms:
f = 8 + -3x-1 + x
