己知XY不等于0,且4X^2-5√3XY+3Y^2=0,求X/Y的值

己知XY不等于0,且4X^2-5√3XY+3Y^2=0,求X/Y的值 已知2x2+5xy-3y2=0且xy不等于0,求x:y的值已知2x2+5xy-3y2=0且xy不等于0,求xy的值 若3x^2+3xy=0且xy不等于0,则x:y= 已知xy不等于0,且2x^2+5xy-3y^2=0,则x^2-y^2/xy的值是? 己知x+y=-4,xy=3,求4(xy+2y)+[6x+（2xy-5y-3x)]的值 已知x-y=3xy,且xy不等于0,则-3x+6xy+3y/(7x-5y)-9xy-(3x-y) 已知x*x-2xy-3y*y=0且x不等于0 y不等于0,那么5x-4y/5x+4y= 己知XY是非0自然数且X不等于Y.X+Y=20.X乘Y积最大最小是多少要列算式 已知x+y=2xy,且xy不等于0,则求-2x+6xy-2y/(7x+5y)-9xy-(3x+y)=___ 已知：x^2 + xy - 6y^2=0,且xy不等于0求2x^2-3xy+y^2/5x^2-7xy+2y^2的值 已知XY不等于0,且3X^2-2XY-8Y^2=0,求x/y的值急啊! 已知 xy不等于0且 3x^2 - 2xy - 8y^2=0求x/y的值! 已知,xy不等于0,且3x方-2xy-8y方=0,则x分之y等于 xy不等于0,且3x平方-2xy-8y平方=0,求x/y得值 已知xy不等于0,且3x² -2xy-8y²=0,求x/y的值 已知x^2-4xy+3y^2=0,且xy不等于0,求x/y+y/x的值 已知x-3y=0,且xy不等于0,求分式x*2-xy+y*2/x*2+xy+y*2的值 已知x-3y=0,且xy不等于0,求分式x^2+xy+y^2分之x^2-xy+y^2的值
