x^2+y^2+1/2=s+y,则x=?,y=?x^2+y^2+1/2=s+y,则x=?,y=?x^2+y^2+1/2=s+y,则x=?,y=?x²+y²+1/2=x+yx&sup

x^2+y^2+1/2=s+y,则x=?,y=?
x^2+y^2+1/2=s+y,则x=?,y=?

x^2+y^2+1/2=s+y,则x=?,y=?
x²+y²+1/2=x+y
x²-x+1/4+y²-y+1/4=0
(x-1/2)²+(y-1/2)²=0
平方数不小于0,要使式子的值为0,则有
x-1/2=0,y-1/2=0
x=1/2,y=1/2

x^2+y^2+1/2 = x+y
x^2 - x + 1/4 + y^2 - y + 1/4 = 0
(x-1/2)^2 + (y-1/2)^2 = 0
如果x, y 是实数
那么 x=y=1/2

x^2+y^2+1/2=x+y
x^2-x+1/4+y^2-y+1/4=0
则(x-1/2)^2+(y-1/2)^2=0
则x=1/2
y=1/2
