3xy and 2xy. You can see that 3xy and 2xy have something in common with each other. They both have xy and the end of them. Hope this helped.

3xy - 3xy = 0
18x3y5 + 9xy3 - 3xy = 3xy(6x2y4 + 3y2 - 1)
3xy-4x + 15y-20 Sol: As there are no number are same. So -4x-3xy +15y-20 -------------------- -4x-3xy+15y-20

3xy + 3y2 = 3y (x + y)

GCF(18xy, 15xy) = 3xy LCM(18xy, 15xy) = 90xy
15x - 3xy = 3x(5 - y) 20 - 4y = 4(5 - y) 15x - 3xy + 20 - 4y = (3x + 4)(5 - y)
