=x^5×(-8y³)+4x²y²(-x³)y
=-8x^5y³-4x^5y³
=-12x^5y³

[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
[(3x+y)(x-y)-(2x+3y)(x-y)]*(x-y)
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
因式分解3x^2(x-y)+6x(y-x)
2X(2X-3Y)-3Y(X+Y)
(-2x y)^2-(3y-x)(-x-3y)
（x+2y)^2-(x+y)(3x-y)
计算(x+y)(x+y)^2(-x-y)^3
化简:5(x-y)+2(x+y)-3(x-y)
3x(x-y)+2y(x-y) 计算
化简3(x-y)-7(x--y)+2(y-x)
