若36x^2-12xy+y^2=0,则x/y+y/x的值是

若36x^2-12xy+y^2=0,则x/y+y/x的值是 若x+y=1,x不等于0则x+(2xy+y^2)/x/(x+y)/x= 若实数x,y满足x^2-xy-y^2 =0,则x/y=? 若y-2x=0,则分式(x^2+xy+y^2)/(x^2-xy+2y^2)= 若|x-3|+（y+2）=0,则（x-y+4xy/x-y）（x+y-4xy/x+y）的值是 若|x-3|+（y+2）²=0,则（x-y+4xy/x-y）（x+y-4xy/x+y）的值是 若x²+xy-2y²=0,则x²+3xy+y²/x²+y² 已知x-xy=20,xy-y=12,则x-y= ,-2xy+x+y= 已知x-xy=20 xy-y=12,则x-y=（ ）,x+y-2xy=（ ）. 已知:x-xy=20,xy-y=12,则x-y=...,-2xy+x+y=... 若x+y-5xy=0,求(2x-3xy+2y)/(x+2xy+y)的值 若2x+y=0,求(x^2+xy+y^2)/(2xy-x^2) 若x+y分之xy=2,则-x+3xy-y分之3x-xy+3y=多少? 若xy/x+y=2,则3x-5xy+3y/-x+3xy-y=?/是分之 若x+y分之xy=2,则-x+3xy-y分之3x-xy+3y=多少? 若xy/x+y=2,则3x-xy+3y/-x+3xy-y= 若集合{x,xy,lg(xy)}={0,|x|,y},求log8(x^2+y^2) {x,xy,lg(xy)}={0,|x|,y} 则log8（X^2+Y^2）
