3X^2+5XY-2Y^2 =
(x+2y)(3x-y)
一个方程两个未知数，，能做？
(x+2y)(3x-y)
题目没说清楚是要解方程还是因式分解
2xy+5y^2+( )=x^2+3xy
已知x^2-xy=5,xy-y^2=-3求3(x^2-xy)-xy+y^2
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)
xy^2=-3,求-xy(x^2y^5-xy^3-y)
已知X-XY-2Y=0求2X+3XY-Y/X-2XY+5Y
若x+y-5xy=0,求(2x-3xy+2y)/(x+2xy+y)的值
已知xy/x+y=3,求代数式2x-5xy+2y/x-3xy+y
已知xy/x+y=2,求代数式3x-5xy+3y/-x+2xy-y的值
已知x+y分之xy=2,那么3x-5xy+3y分之3xy-x-y=
若xy/x+y=2,则3x-5xy+3y/-x+3xy-y=?/是分之
如果xy/x+y=2,那么3x-5xy+3y/-x+3xy-y=?
已知xy/x+y=1/2,则代数式3x-5xy+3y/-x+3xy-y=
已知Y-x=3xy,求(5x+3xy-5y)÷(x-2xy-y)
当x+y=5xy时,（3x+xy+3y)/x-2xy+y=?
xy/x+y=2 求3x-5xy+3y/-x+3xy-y的值?
若xy=2（x+y),求 （3x-5xy+3y)÷(-x+3xy-y) 的值
