计算:(x-2y)(x+y)-2y(1-4y)=计算:(x-2y)(x+y)-2y(1-4y)=计算:(x-2y)(x+y)-2y(1-4y)=（x-2y）(x+y)-2y(1-4y)=x²
计算:(x-2y)(x+y)-2y(1-4y)=
计算:(x-2y)(x+y)-2y(1-4y)=
计算:(x-2y)(x+y)-2y(1-4y)=
（x-2y）(x+y) - 2y(1-4y)
=x²+xy-2xy-2y²-2y+8y²
=x² - xy+6y²-2y
化简得x^2 6y^2-3xy-2y
计算:y-x分之x+y+x-y分之y-y-x分之2x-y
计算：[(x+y)(x-y)-(x-y)^2+2y(x-y)]/(-2y)
(x+y)(x-y)-(2x+y)(x-y+1)计算要过程
计算:(x+2y)(2x-y)
计算:(x+3y)(2x-y)
计算:(2x-3y)(x+y)
计算:(-x-2y) * (3x-y)
计算：(x+y)-3(x-2y).
计算(x+y-1)^2
计算:(x-y)^2*(y-x)^2*(x-y)^6
计算(x-y)(y^2-x^2)(-x-y)
计算(x+y)(x+y)^2(-x-y)^3
3x(x-y)+2y(x-y) 计算
计算：（x-y）^2-(x+y)(x-y)
（x-2y）(x+y)+（x+y）计算
计算[2x^2-(x+y)(x-y)][(-x-y)(y-x)+2y^2]
计算：x+2y/x-y+2x/y-x-3y/x-y
计算2/3x-2/x+y(x+y/3x-x-y)/x-y/x
