    3y (6x-3w-4)

    Step-by-step explanation:

    18xy - 9wy - 12y

    18xy = 3*3*2*x*y

    9wy = 3*3*w*y

    12y = 3*2*2*y

    We can factor out a 3 and a y

    3*3*2*x*y - 3*3*w*y - 3*2*2*y

    3y (3*2*x - 3*w - 2*2)

    3y (6x-3w-4)

    A

    Step-by-step explanation:

    18xy-9wy-12y only have 3y in common so you divide them by 3y which is 3y (6x-3w-4).

    this is the simplest form, the remaining doesn't have nothing in commun to factor.
