Simplifying f(x) = 4x2 + 40x + 3 Multiply f * x fx = 4x2 + 40x + 3 Reorder the terms: fx = 3 + 40x + 4x2 Solving fx = 3 + 40x + 4x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = 3x-1 + 40 + 4x Simplifying f = 3x-1 + 40 + 4x Reorder the terms: f = 40 + 3x-1 + 4x
