v%5B1%2C2%5D = %28-12+%2B-+sqrt%2812%5E2+%2B+4%2A1%2A220%29%29%2F2 = %28-12+%2B-+sqrt%28144%2B880%29%29%2F2 = %28-12+%2B-+sqrt%281024%29%29%2F2 = %28-12+%2B-+32%29%2F2.


There are two roots:  v%5B1%5D = %28-12%2B32%29%2F2 = 20%2F2 = 10,  and

                      v%5B2%5D = %28-12-32%29%2F2 = -44%2F2 = -22.
