-1f * x + -1f(x) = 3x3 + -6x2 + -8x + -14 + -1(-3x3 + 6x2 + 8x + -14)

Multiply f * x
-1fx + -1f(x) = 3x3 + -6x2 + -8x + -14 + -1(-3x3 + 6x2 + 8x + -14)

Multiply f * x
-1fx + -1fx = 3x3 + -6x2 + -8x + -14 + -1(-3x3 + 6x2 + 8x + -14)

Combine like terms: -1fx + -1fx = -2fx
-2fx = 3x3 + -6x2 + -8x + -14 + -1(-3x3 + 6x2 + 8x + -14)

Reorder the terms:
-2fx = 3x3 + -6x2 + -8x + -14 + -1(-14 + 8x + 6x2 + -3x3)
-2fx = 3x3 + -6x2 + -8x + -14 + (-14 * -1 + 8x * -1 + 6x2 * -1 + -3x3 * -1)
-2fx = 3x3 + -6x2 + -8x + -14 + (14 + -8x + -6x2 + 3x3)

Reorder the terms:
-2fx = -14 + 14 + -8x + -8x + -6x2 + -6x2 + 3x3 + 3x3

Combine like terms: -14 + 14 = 0
-2fx = 0 + -8x + -8x + -6x2 + -6x2 + 3x3 + 3x3
-2fx = -8x + -8x + -6x2 + -6x2 + 3x3 + 3x3

Combine like terms: -8x + -8x = -16x
-2fx = -16x + -6x2 + -6x2 + 3x3 + 3x3

Combine like terms: -6x2 + -6x2 = -12x2
-2fx = -16x + -12x2 + 3x3 + 3x3

Combine like terms: 3x3 + 3x3 = 6x3
-2fx = -16x + -12x2 + 6x3

Solving
-2fx = -16x + -12x2 + 6x3

Solving for variable 'f'.

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