化简x²/(y-x)+y²/(x-y)的结果是
化简x²/(y-x)+y²/(x-y)的结果是

化简x²/(y-x)+y²/(x-y)的结果是
x²/(y-x)+y²/(x-y)
=x²/(y-x)-y²/(y-x)
=(x²-y²)/(y-x)
=[(x+y)(x-y)]/(y-x)
=-(x+y)
=-x-y

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

= -x^2/(x-y)+y^2/(x-y)
=(y^2-x^2)/(x-y)
=-(y+x))(x-y)/(x-y)
=-(y+x)
=-y-x

原式=x²/(y-x)+(-y²)/[-(x-y)]
=x²/(y-x) - y²/(y-x)
=(x²- y²)/(y-x)
=(x-y)(x+y)/(y-x)
= -x-y
