x*x+xy=3,xy+y*y=2,则x*x+2xy+y*y=________?
|x|/x+y/|y|+xy/|xy|=
f(xy,x-y)=x^2+3xy+y^2,则f(x,y)=?
已知x+xy+y=3,则(3x+2xy+3y)/(2x+xy+2y)=
已知x-y=3xy,则2x+3xy-2y除以x-2xy-y=?
已知x-y=3xy,则2x+3xy-2y/x-2xy-y=
若x+y分之xy=2,则-x+3xy-y分之3x-xy+3y=多少?
若xy/x+y=2,则3x-5xy+3y/-x+3xy-y=?/是分之
若x+y分之xy=2,则-x+3xy-y分之3x-xy+3y=多少?
已知xy/x+y=1/2,则代数式3x-5xy+3y/-x+3xy-y=
若xy/x+y=2,则3x-xy+3y/-x+3xy-y=
已知xy/x+y=3,则代数式2x-7xy+2y/-x+xy-y的值是多少?
(-3x^y+2xy)-( )=4x^+xy
若x-y=4,xy=1,则(2x+y-2xy)-(3x+2y+xy)-(4xy+3y-5x)=
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
已知x+y=1,xy=-2,则x²y+xy²-2xy
当x-y=2xy时,求4x-3xy-4y/xy
函数f(xy,x+y)=x^2+xy+y^2,则df(x,y)=?
