若实数x,y满足x^2+xy-x^2=0,则x/y的值为应该是x^2+xy-y^2

若实数x,y满足x^2-xy-y^2 =0,则x/y=? 若实数x,y满足xy>0,且x^2y=2,则xy+x^2的最小值 若实数x,y满足xy>0,且x²y=2,则xy+x²的最小值是? 若正实数x.y满足x+y=xy,则x+2y的最小值 若两个正实数x,y满足x^2+2xy-3y^2=0,求x^2+xy+y^2/x^2-xy+y^2 若正实数x,y满足2x+y+6=xy,求xy的最小值. 若正实数X,Y满足2X+Y+6=XY,求XY的最小值. 已知实数xy满足x+2y 已知实数xy满足 x+y-2 若实数x,y满足x^2+xy-x^2=0,则x/y的值为应该是x^2+xy-y^2 若实数X,Y满足X^2+Y^2+2XY+X-Y=0,则Xmax= ,Xmin= 若实数X,Y满足X^2+Y^2+2XY+X-Y=0则Xmax= ,Xmin= 若实数xy满足x^2+y^2-2x+6y=0 则x-2y的最大值 若实数x,y满足x的平方+xy-2y的平方=0,则x/y= 若实数x,y满足x的平方+xy+2y的平方=0,则x/y= 若实数xy满足（x+y+2)(x+y-1)=0,则x+y的值是 已知实数x,y满足x²+y²-xy+2x-y+1=0 求x y 若实数x,y满足根号x-2 +(3-y)^2=0,则代数式xy-x的值为
