Simplifying f(x) = [x + 1] + [x + -2] Multiply f * x fx = [x + 1] + [x + -2] Reorder the terms: fx = [1 + x] + [x + -2] Remove brackets around [1 + x] fx = 1 + x + [x + -2] Reorder the terms: fx = 1 + x + [-2 + x] Remove brackets around [-2 + x] fx = 1 + x + -2 + x Reorder the terms: fx = 1 + -2 + x + x Combine like terms: 1 + -2 = -1 fx = -1 + x + x Combine like terms: x + x = 2x fx = -1 + 2x Solving fx = -1 + 2x Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = -1x-1 + 2 Simplifying f = -1x-1 + 2 Reorder the terms: f = 2 + -1x-1
