-2f2x = -2 + x + x2

Solving for variable 'f'.

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

Divide each side by '-2x'.
f2 = x-1 + -0.5 + -0.5x

Simplifying
f2 = x-1 + -0.5 + -0.5x

Reorder the terms:
f2 = -0.5 + x-1 + -0.5x

Reorder the terms:
0.5 + f2 + -1x-1 + 0.5x = -0.5 + x-1 + -0.5x + 0.5 + -1x-1 + 0.5x

Reorder the terms:
0.5 + f2 + -1x-1 + 0.5x = -0.5 + 0.5 + x-1 + -1x-1 + -0.5x + 0.5x

Combine like terms: -0.5 + 0.5 = 0.0
0.5 + f2 + -1x-1 + 0.5x = 0.0 + x-1 + -1x-1 + -0.5x + 0.5x
0.5 + f2 + -1x-1 + 0.5x = x-1 + -1x-1 + -0.5x + 0.5x

Combine like terms: x-1 + -1x-1 = 0
0.5 + f2 + -1x-1 + 0.5x = 0 + -0.5x + 0.5x
0.5 + f2 + -1x-1 + 0.5x = -0.5x + 0.5x

Combine like terms: -0.5x + 0.5x = 0.0
0.5 + f2 + -1x-1 + 0.5x = 0.0

The solution to this equation could not be determined.
