1. ## Factoring expressions

I need to completely factor this expression:

$5(6-5s)^2 + 6(7s-2)(6-5s)$

I see the similarities of the $(6-5s)$ but I don't know what to do about it. If anyone could help me out I'll be grateful! Thanks

2. = (6 - 5s)(5(6 - 5s) + 6(7s -2))
= (6 - 5s)(30 - 25s +42s - 12)
= (6 - 5s)(18 - 17s)

3. You flubbed slightly on your negative/positive signs, but I got the gist and you're right! Thanks muchly
