x²-y²/xy - xy-y²/x(y-x)

x²-y²/xy - xy-y²/x(y-x)
x²-y²/xy - xy-y²/x(y-x)

x²-y²/xy - xy-y²/x(y-x)
=(x²-y²)/xy-y(x-y)/x(y-x)
=(x²-y²)/xy+y(x-y)/x(y-x)

=(x²-y²)/xy+y/x
=(x²-y²+y²)/xy
=x/y

x²-y²/xy - xy-y²/x(y-x)=x²求解，求过程。。。y²/xy=y/x xy-y²=y(x-y)，故xy-y²/x(y-x)=-y/x 如果我没说错，这里xy-y²应该用括号括起来 故-y²/xy-xy-y²/x(y-x)=0 则有x²-y²/x...

x²-y²/xy - xy-y²/x(y-x)=x²

结果是x/y，左边分母不同分，右边分子提取y，然后右边分子分母可以约去（x-y）且前面的符号变为正，然后分子分母同时乘以y。然后加起来就是可以很容易看到结果

能否说的详尽些？比如要求什么？化简？还有分母能否加个括号？看不清
