已知x²+y²-8x+6y+25=0,求(x-y+4xy/x-y)(x+y-4xy/x+y)
x-y/x²÷x²-2xy+y²/xy*(xy-x²)
2x²-3xy=y²=0(x,y不得o)求x/y+y/x
[x(x²y²-xy)-y(x²-x³y)]÷3x²y
因式分解:[x(x²y²-xy)-y(x²-x³y)]÷3x²y
化简 (x+y)(x²-xy+y²) ; 3(2x-1)(x+6)-5(x-3)(x+6)
2.(x+y)²(x-y)²-(x-y)(x+y)(x²+y²)
3x²y+xy²-[2xy²-4x²y+(x²y-2xy²)
化简:(x²+y²/x-y)-(2xy/x-y)
2x+2y/x-y与(x²+y²)/xy通分
(x-y)/(2x+2y)与(xy)/(x+y)²通分要过程
(x+y)(x²-xy+y²)—xy(x+y)因式分解
