Simplifying f(x) = x2 + 5x + 6.25 Multiply f * x fx = x2 + 5x + 6.25 Reorder the terms: fx = 6.25 + 5x + x2 Solving fx = 6.25 + 5x + 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 = 6.25x-1 + 5 + x Simplifying f = 6.25x-1 + 5 + x Reorder the terms: f = 5 + 6.25x-1 + x
