3xy-2x-4=0,... so taking the dirividive of y using newtons it would be(3y)(3xy') -2=0 which could be called9 xyy'-2=0.. remember you Are trying to isolate the y prime. so bring the 2 over first.9xyy'=2.....then divide by 9xyy'=(2)/(9xy).....so then just plug in your variables and presto
3xy
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.

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)
