Simplifying f(x) = 2x2 + x + 15 Multiply f * x fx = 2x2 + x + 15 Reorder the terms: fx = 15 + x + 2x2 Solving fx = 15 + x + 2x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = 15x-1 + 1 + 2x Simplifying f = 15x-1 + 1 + 2x Reorder the terms: f = 1 + 15x-1 + 2x
