Simplifying f(x) = 5x2 + 2x + 1 Multiply f * x fx = 5x2 + 2x + 1 Reorder the terms: fx = 1 + 2x + 5x2 Solving fx = 1 + 2x + 5x2 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 + 5x Simplifying f = x-1 + 2 + 5x Reorder the terms: f = 2 + x-1 + 5x
