15ma-2nb-3bn+10am=15ma+10am-2nb-3bn
=25am-5bn
=5(5am-bn)
2xy-2x+6-6y
=2x(y-1)+6(1-y)
=(y-1)(2x-6)
=2(x-3)(y-1)

15ma-2nb-3bn+10am
=25am-5bn
=5(5am-bn)
2xy-2x+6-6y
=2(xy-x+3-3y)
=2[x(y-1)+3(1-y)]
=2[x(y-1)-3(y-1)]
=2(y-1)(x-3)
=25am-5bn
=5(5am-bn)
2xy-2x+6-6y
=2(xy-x+3-3y)
=2[x(y-1)+3(1-y)]
=2[x(y-1)-3(y-1)]
=2(y-1)(x-3)
