关于分式约分题,
1.x²-y²/x²+2xy+y²
2.x²+4x+3/ x²+x-6
3.m²+3m/9-m²

1.x²-y²/x²+2xy+y²
=(x-y)(x+y)/(x+y)^2
=(x-y)/(x+y)
2.x²+4x+3/ x²+x-6
=(x+1)(x+3)/(x+3)(x-2)
=(x+1)/(x-2)
3.m²+3m/9-m²
=m(m+3)/(3+m)(3-m)
=m/(3-m)

数学分式通分与约分约分 (x²+xy)/(x+y)² x²-y²/（x² 分式的约分与通分问题约分 (x²+xy)/(x+y)² x²-y²/（x&sup 3x²-4xy+y² x/y=2,求分式x²-xy+3y²/x²+xy+6y² 计算:(1).(-2xy²)*(3x²y)² x²-4y²/x²+2xy+y²÷x+2y/2x²+2xy 代数分式一道题若x÷y=2,则分式（x²-xy+3y²)÷（x²＋xy＋6y² 分式的除法运算x²－4y²/x²+y²+2xy÷2y+x/x²+xy 1-x²+2xy-y² 分式的乘除法计算：：x²-4y²/x²+2xy+y²÷x+2y/x²+ x²+y²+4x-8y+20=0,求分式x²-y²/xy的值先化简,再求值：3xy²(-x²y+2x³y²)-4xy(-xy²)·
