Simplifying f(x) = x2 + -2x + 1 Multiply f * x fx = x2 + -2x + 1 Reorder the terms: fx = 1 + -2x + x2 Solving fx = 1 + -2x + 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 = x-1 + -2 + x Simplifying f = x-1 + -2 + x Reorder the terms: f = -2 + x-1 + x
