    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

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