因式分解:3xy(x-y)+6y(y-x)因式分解:3xy(x-y)+6y(y-x)因式分解:3xy(x-y)+6y(y-x)原式=3xy(x-y)-6y(x-y)=(3xy-6y)(x-y)=3y(

因式分解:3xy(x-y)+6y(y-x)
因式分解:3xy(x-y)+6y(y-x)

因式分解:3xy(x-y)+6y(y-x)
原式=3xy(x-y)-6y(x-y)
=(3xy-6y)(x-y)
=3y(x-2)(x-y)

=3xy(x-y)-6y(x-y)
=(x-y)(3xy-6y)
3y(x-y)(x-2)

原式=3xy(x-y)-6y(x-y)
=(3xy-6y)(x-y)
=3(xy-2y)(xy)
