-X^2-Y^2-2XY
-X^2-Y^2-2XY
-X^2-Y^2-2XY
原式=-(X+Y)^2
-X^2-Y^2-2XY
=-(X^2+Y^2+2XY)
=-(X+Y)^2
x^2-xy/xy-y^2约分
(x^2+xy/x-y)/(xy/x-y)计算
(-x-y)(x^2+xy+y^2)
化简x^-y^/x^-2xy+y^
2*(x-y)²(y-x)(xy)
.(x+y-2)(x+y-2xy)+(xy-1)^2
(x^2-xy)y÷y-x/xy怎么做?
2x²y-3(2xy-xy)-xy
(x^2+2xy+y^2-4xy)*(x^2-2xy+y^2+4xy)
(y/(x^2-xy)+x/(y^2-xy))除以(x-y)/(xy)
(xy-x²)÷(x²-2xy+y²/xy)×(x-y/x²)
x-y/x²÷x²-2xy+y²/xy*(xy-x²)
初二数学化简分式x^2 -y^2/xy - xy-y^2/xy-x^2x^2 -y^2/xy - xy-y^2/xy-x^2
代数 x^-y^/ x^-(y-z)^ 除以 x^+2xy+y^/(x-y)^-z^ 乘 x^+xy-xz/x^-xy
x^2-xy-6y^2+3xy+y+2
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
(x-y)[(x+y)^2-xy]+(x-y)[(x-y)^2+xy]
计算(xy-y^2)÷x-y/xy
