y^2=xy=x^2y^2=xy=x^2y^2=xy=x^2y=x²则y²=x^4=xx(x³-1)=0x(x-1)(x²+x+1)=0x²+x+1=
y^2=xy=x^2
y^2=x
y=x^2
y^2=xy=x^2
y=x²
则y²=x^4=x
x(x³-1)=0
x(x-1)(x²+x+1)=0
x²+x+1=0无解
所以x=0,x=1
y=x²
所以
x=0,y=0
x=1,y=1
(-3x^y+2xy)-( )=4x^+xy
(XY-X^2)除以X-Y/XY=?
x*x+xy=3,xy+y*y=2,则x*x+2xy+y*y=________?
X²+2xy+y²/xy乘x²-2xy+y²/xy+y²=
[-xy^2(2x+y)-8xy)-x^2y)]除以2xy=计算
已知x+y=1,xy=-2,则x²y+xy²-2xy
已知x-xy=8,xy-y=-9,求x+y-2xy的值
1-2/x+y=xy,4y+6x=xy.求xy的解?
y/x=ln(xy) 求dy/dx(xy-y^2)/(xy+x^2)
当x-y=2xy时,求4x-3xy-4y/xy
若1/x-1/y=2,求3x-2xy-3y/x-xy-y的值3x-2xy-3y/x-xy-y 不好意思,是3x-2xy-3y/x-2xy-y
由已知x+y=-2,xy=3那么2(x+xy)-[(xy-3y)-x]-(-xy)等于多少?
x^2+xy+x=36,y^2+xy+y=20,求x+y.
若x^2+xy+y=14,y^2+xy+x=28,求x+y
函数f(xy,x+y)=x^2+xy+y^2,则df(x,y)=?
f(xy,x-y)=x^2+3xy+y^2,则f(x,y)=?
f(xy,x-y)=x^2+y^2+xy;f(x,y)/∂x;f(x,y)/∂y
如果x^2+xy+y-14,y^@+xy+x=28,求x+y的值.
