Answer 6

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

Answer 7

*two

Answer 8

use what @Mertsj said

Answer 9

Factor out 6 first

Answer 10

okay. and after that?

Answer 11

6 times (x+11) times (x-7)

Answer 12

i still don't understand... @Mertsj

Answer 13

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)

Answer 14

oh okay ... i understand it much better now. :) thanks @CasidyCat

Answer 15

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