送分呃...告诉偶啊...化简分式(X-Y+4XY/X-Y)(X=Y-4XY/X+Y)的结果是?10.点#35
已知x*x-4xy+4y*y=0 求[2x(x+y)-y(x+y)]/(4x*x-4xy+y*y)的值?
1/x-1/y=4,求分式(3x+xy-3y)/(x-2xy-y)
分式y/2x,x/3y^2,1/4xy的最简公分母是什么
分式x/2y,y/3x*2,1/4xy的最简公分母
分式2/xy,3/x+y,4/x-y的最简公分母是什么
化简分式方程:x*x-xy-y*y/x*x-3x-6y+2xy
已知xy/x+y=二分之一,求分式3x-xy+3y/x-xy+y的值
若(y-x)/xy=3,求分式(2x+3xy-2y)/(x-2xy-y)的值
已知x-y/xy=3,求分式2x+3xy-2y/x-2xy-y的值.
以知x^2-4xy+4y^2=0,那么分式(X+Y)/(X-Y)的值等于?
若x+y+4x-8y+20=0,求分式(x-y)/xy的值
x²+y²+4x-8y+20=0,求分式x²-y²/xy的值
