Two numbers r and s sum up to 10 exactly when the average of the two numbers is \frac{1}{2}*10 = 5. 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.Popular Problems Algebra Solve by Factoring x^2-x-2=0 x2 − x − 2 = 0 x 2 - x - 2 = 0 Factor x2 − x−2 x 2 - x - 2 using the AC method.
