化简：（x-3y）^2 -(x-3y)(x+3y)
化简：（x-3y）^2 -(x-3y)(x+3y)
化简：（x-3y）^2 -(x-3y)(x+3y)
（x-3y）^2-(x-3y)(x+3y)
=(x-3y)[(x-3y)-(x+3y)]
=(x-3y)(x-3y-x-3y)
=(x-3y)(-6y)
=18y^2-6xy
化简：{2/3x-2/(x+y)[(x+y)/3x-x-y]}/(x+y)/x
化简3x-2/(x+y)[(x+y)/3x-x-y]÷(x-y)/x
化简:(x-3y)(x+y)-(x-2y)(x+2y)-(x-y)平方
化简:5(x-y)+2(x+y)-3(x-y)
化简3(x-y)-7(x--y)+2(y-x)
