若x^2+y^2+2x-36y+10=0 求x-y/x+y的值

应该是抄写错误，应该是：
x^2+y^2+2x-6y+10=0 求x-y/x+y的值
只有这样才能做，不然没解
x^2+y^2+2x-6y+10=0
x^2+2x+1+y^2-6y+9=0
(x+1)^2+(y-3)^2=0
x+1=0 x=-1
y-3=0 y=3
所以原式=（-1-3）/（-1+3）=-2

(2x+y)(2x-y)-(3x-2y)(x+y)-y(2x-y) (x-2y)^2+(x-y)(x-2y)-2(x-3y)(x-y) 若3x-2y=0,求(x+y)/(x-y)+(x-y)/(x+y)的值 x^2+3(x+y)+3-y^2+(x-y) 3X(X-Y)+2Y(X-Y) (x+y)(x-y)=(x+y)2 3(x+y)(x-y)+4(x-y)^2=? (X-3y)(x+3y)-(x-3y)^2 (x+y)^2(x-y)^2 (x+y)^2×(x-y)^2=?
