若x^2+y^2-10x-2y+26=0求根号x/4+根号y/2注：1.x/4在根号内,y/2也是 2.速度! 3.拜托~

x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2 若x-y不等于0,2x-3y=0,则分式(10x-11y)/(x-y)的值是（）?(10x-11y)/(x-y) =[(8x-8y)+(2x-3y)]/(x-y) =8为什么8X-8Y=8？(10x-11y)/(x-y)=[(8x-8y)+(2x-3y)]/(x-y)=8+(2x-3y)]/(x-y)=8+0=8 若(x*x+y*y)(x*x+y*y)-4x*x*y*y=0,求代数式(x*x+5xy+y*y)/(x*x+2xy+y*y)的值 若x^2+y^2-10x-6y+34=0,求（x-y)/(x+y)的值 若x^2+2x+y^2-6y+10=0,则x-y 若x^2+y^2-10x+6y+34=0,则x+y=? 若x²+2x+y²-6y+10=0求x y 若x.y满足条件2x+y-12=0,x-4y+10 若x^2-4x+y^2-10y+29=0,求x^2y^2+2x^3y^2+x^4y^2的值 若X^2+Y^2+2X-6Y+10=0,先化简X+Y分之Y^2,分之X-Y分之X-1 若|x+y-1|+（x-y-2)²=0,求代数式（x+2y)(x-2y）-（2x-y)(-y-2x)的值. 若3x-5y=0,则x+y/x=（）,x-y/y=（）,2x-3y/2x+3y=( ) 若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值 {4x-3y-10=0 3x-2y=0,{3x-4(x-y)=2 2x-3y=1,{2(x+y)-(x-y)=3 (x+y)-2(x-y)=1 若实数x,y满足x²+y²-10x-2y+26=0 ,求根号下x²y²的值 若实数x,y满足x²+y²-10x-2y+26=0,求√x²y² (X,Y) f(x,y)={12y^2,0 已知x>0,Y>0,如何证x^2/y+y^2/x>=x+y
