[3x^2-(x+y)(y-x)][2(-x-y)(y-x)+2x^2+3y^2] =(3x^2+x^2-y^2)(2x^2-2y^2+2x^2+3y^2) =(4x^2-y^2)(4x^2+y^2) =16x^4-y^4
x(x-y)2-(y-x)3
[2/3x-2/x+y(x+y/3x-x-y)]/x-y/x
化简：{2/3x-2/(x+y)[(x+y)/3x-x-y]}/(x+y)/x
计算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
计算：x+2y/x-y+2x/y-x-3y/x-y
化简:(x-3y)(x+y)-(x-2y)(x+2y)-(x-y)平方
[(3x+y)(x-y)-(2x+3y)(x-y)]*(x-y)
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
化简y(x+y)+(x+y)(x-y)-x^2
因式分解x(x+y)(x-y)-x(x+y)^2
