已知x+y=5,xy=2则x^2y+xy^2=()已知x+y=5,xy=2则x^2y+xy^2=()已知x+y=5,xy=2则x^2y+xy^2=()x²y+xy²=xy(x+y)
已知x+y=5,xy=2则x^2y+xy^2=( )
已知x+y=5,xy=2则x^2y+xy^2=( )
已知x+y=5,xy=2则x^2y+xy^2=( )
x²y+xy²=xy(x+y)=10
已知xy/x+y=1/2,则代数式3x-5xy+3y/-x+3xy-y=
已知x+y=1,xy=-2,则x²y+xy²-2xy
已知x+y=5,xy=2则x^2y+xy^2=( )
已知x+y=1,xy=1/5,则x^2y=xy^2
已知x+y=5,xy=-3,则x^2y+xy^2,
已知xy/x+y=2,则代数式3x-5y+8y/-x+3xy-y的值
已知xy^2=-2,求-xy(x^2y^5-xy^3-y)的值.
已知xy^2=-2 求-xy(x^2y^5-xy^3-y)
已知xy^2=-2xy(x^2y^5-xy^3-y)
已知x^2-xy=5,xy-y^2=-3求3(x^2-xy)-xy+y^2
已知:x²-xy=9,xy-y²=5,则x²-2xy+y²=(),3x²+xy-2y²+()
已知x+y+2=2xy,则4x-5xy+4y+8=( )xy过程 .谢谢
已知x-xy=10,xy-y=2,则x-y=( ),-2xy+x+y=( ).
已知x-y=3xy,则2x+3xy-2y除以x-2xy-y=?
已知x+xy+y=3,则(3x+2xy+3y)/(2x+xy+2y)=
已知x-y=3xy,则2x+3xy-2y/x-2xy-y=
已知x-xy=20,xy-y=-10,则x-y=( ),x+y-2xy=( ).
已知x-xy=20,xy-y=12,则x-y= ,-2xy+x+y=
