Two numbers r and s sum up to -\frac{7}{2} exactly when the average of the two numbers is \frac{1}{2}*-\frac{7}{2} = -\frac{7}{4}. You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C. Since 2x2 +4 2+7x−4x2 2 x 2 + 4 2 + 7 x - 4 x 2 → → ∞ ∞ as x x → → 2 2 from the left and 2x2 +4 2+7x−4x2 2 x 2 + 4 2 + 7 x - 4 x 2 → → −∞ - ∞ as x x → → 2 2 from the right, then x = 2 x = 2 is a vertical asymptote. x = 2 x = 2.
