xy(x-y)-x(x-y)²
= x(x-y)[y-(x-y)]
= x(x-y)(y-x+y)
= x(x-y)(2y-x)
= x(x-y)[y-(x-y)]
= x(x-y)(y-x+y)
= x(x-y)(2y-x)

xy(x-y)-x(x-y)²
=x(x-y)[y-(x-y)]
=x(x-y)(-x)
=-x^2(x-y)
=x(x-y)[y-(x-y)]
=x(x-y)(-x)
=-x^2(x-y)

xy(x-y)-x(x-y)²
=(x-y)[xy-x(x-y)]
=(x-y)(2xy-x^2)
=x*(x-y)*(2y-x)
=(x-y)[xy-x(x-y)]
=(x-y)(2xy-x^2)
=x*(x-y)*(2y-x)

解答:
xy(x-y)-x(x-y)^2=x(x-y)(y-x+y)=x(x-y)(2y-x)
xy(x-y)-x(x-y)^2=x(x-y)(y-x+y)=x(x-y)(2y-x)
