Simplifying f(x) = x2 + 2x + 3g(x) * x + 2 Multiply f * x fx = x2 + 2x + 3g(x) * x + 2 Multiply g * x fx = x2 + 2x + 3gx * x + 2 Multiply gx * x fx = x2 + 2x + 3gx2 + 2 Reorder the terms: fx = 2 + 3gx2 + 2x + x2 Solving fx = 2 + 3gx2 + 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 = 2x-1 + 3gx + 2 + x Simplifying f = 2x-1 + 3gx + 2 + x Reorder the terms: f = 2 + 3gx + 2x-1 + x
