Well...what would you like to do here?
You can't solve this since the there is no equation!
The only thing you can do is to factor this expression, so let's do that!
Factor the expression:

Start with Now you need to have m and n such that:
(m)(n) = 21 and 2m+n = 17 or m+2n = 17
Try m =3 and n = 7
(3)(7) = 21 OK
2(3)+7 = 6 + 7 = 13 No good.
3 + 2(7) = 3 + 14 = 17 OK
That'll do it.
