由x+y=xy可得 x=y(x-1) 即有 y=x/(x-1)
然后随便代个数到函数 就ok
如 令 x=3 则y=3/2
|x|/x+y/|y|+xy/|xy|=
已知x*x-4xy+4y*y=0 求[2x(x+y)-y(x+y)]/(4x*x-4xy+y*y)的值?
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
已知,x²+xy=14,y²+xy=2(x>y>0)求x+y.x-y
已知,x²+xy=14,y²+xy=2(x>y>0)求x+y.x-y
已知,x²+xy=14,y²+xy=2(x>y>0)求x+y.x-y
已知x-2y=0,求(x/y-y/x)乘xy/x^2-2xy+y^2
f(xy,x-y)=x^2+y^2+xy;f(x,y)/∂x;f(x,y)/∂y
(x+y)^2/y^2-xy÷[-y^2+xy/(x-y)^2,x=0,y=根号10
x*x+xy=3,xy+y*y=2,则x*x+2xy+y*y=________?
若2x+y=0,求(x^2+xy+y^2)/(2xy-x^2)
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)
x+y=-3 xy+x+y=-2 x/y+y/x=?
已知x-3y=0,求(2x+y)/(x^2-2xy+y^2)X(x-y)
X×X-2XY-Y×Y+2X-2Y+2=02X×2X-4XY-2Y×2Y+3X-3Y+4=0X×X+2XY+Y×Y+X+Y-56=0X×X-2XY+Y×Y-X+Y-12=0X×X-3XY+Y×Y=-13X×3X-XY+3Y×3Y=13 两个在一起的方程之间有所联系(要求一步一步写出来)
(-x+2y)(2x+y)-(2x+y)(y-2x)-3xy=?因式分解
f(x+y,x-y)=(x^2-y^2)/2xy,求f(x,y)!
