i found the factors of 462: 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462 but i need to find tow factors that when combined will be 24

6x2+24x−462 can be simplified to 6(x2+4x-77) Then x2+4x-77 can be made into (x+11)(x-7) Then add the 6 from before 6(x+11)(x-7)

The end simplification is basically that you had two find two factors of 77 that added up to 4. This will work on most. :)
