discriminant of the quadratic equation,    b2 -4ac ,   must be > zero 

                              452 - 4(8)(c) >0

                             2025 - 32c > 0

                                  32c<2025

                                      c < 63.28         the product of 1 thru 63   is a big number.....did you enter the correct numbers in your Q ?

63! = 1.982608315 x 1087
