若x,y满足x^+2y^-2xy+1=0,求xy的值

若x,y满足x^+2y^-2xy+1=0,求xy的值 若实数x,y满足x^2-xy-y^2 =0,则x/y=? 若正整数X,Y满足2X+Y--XY=0,求X+Y的最小值 若xy满足x²+2x+y-2√y-1=-1,求xy, 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x,y满足x的平方+2y的平方-2xy-2y+1=0,求（x+y)的xy次方的值. 已知实数xy满足x²﹢y²-xy+2x-y+1=0求xy 若正实数x.y满足x+y=xy,则x+2y的最小值 已知正整数x,y满足：xy-x-y=0,则x+2y的最小值 已知正数x,y满足2x+8y-xy=0,x+y的最小值 若x.y满足x+=4和x-y=2,求xy分之2x-y+1除以-x分之y+y分之x的值 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? 如果有理数x y 满足|x-1|+|xy-2|=0,求xy的绝对值 已知实数xy,满足10x²-2xy+y²+6x+1=0,求x+y 若正数x,y满足x^2+3xy-1=0,则x+y的最小值是
