Answer 5

Answer 6

I TOLD YOU!!!! 6&7

Answer 7

ok geez dang :(

Answer 8

unlike ppl i like to start from the beginning

Answer 9

so u split the middle term like this 13x = 6x+7x got this ?

Answer 10

Hmm, well perhaps you can write a factor tree for 42

42 1
21 2
14 3
7 6 <---

to show that's how you get your 2 numbers

Then just write them as the factors

\[\large (x + 7)(x + 6)\]

Answer 11

Do i continue?

Answer 12

@haleyelizabeth2017 ??

Answer 13

^ Of course, many different ways to do this

Answer 14

oh ok

Answer 15

ok you should get x^2+6x+7x+42

Answer 16

now group two terms at a time and see what u can factor out
what u see common in
x^2+6x ?

Answer 17

sorry....had to take a call.....working for my mom right now as well as school

Answer 18

from x^2 + 6x , you can factor out x, right ? so u get x(x+6) got this?

Answer 19

@haleyelizabeth2017 ?

Answer 20

I got it :/

Answer 21

well if you got it, what about 7x +42?

Answer 22

dayum....can't leave a second and you're calling me back :P lol umm.......heehee thats unfair! 7(x+6)?

Answer 23

write 42 as just 7*6 then u get 7x+7*6 7(x+6) got this ?

Answer 24

lol

Answer 25

so you will conclude with (x+6)(x+7)

Answer 26

how though?!?!?!?!?!?!?!?!? I DON'T GET THAT PART!!!! How do you go from x(x+6) and 7(x+6) to (x+6)(x+7)?????

Answer 27

@haleyelizabeth2017 Ok lets go back and dont need to get so excited i am just merely helping.

Answer 28

and how did you go from 13x=6x+7x to \(x^2+6x+7x+42\)?
