Ответ:

Объяснение:

$(\frac{y^{2} }{x(x^{2} -y^{2})}+\frac{1}{x+y} } )/(\frac{x-y}{x(x+y)} -\frac{x}{y(x+y)} )\\(\frac{y^{2} }{x(x-y)(x+y)}+\frac{1}{x+y} } )/(\frac{y(x-y)-x^{2} }{xy(x+y)} )\\\\\\\frac{y^{2}+x(x-y) }{x(x-y)(x+y)}/\frac{xy-y^{2}-x^{2} }{xy(x+y)} \\\frac{y^{2}+x^{2} -xy}{x(x-y)(x+y)}/\frac{xy(x+y) }{xy-y^{2} -x^{2} } \\\\\frac{-(xy-y^{2}-x^{2} ) }{x-y}*\frac{y}{xy-y^{2} -x^{2} } \\\frac{-1}{x-y} *y\\-\frac{y}{x-y}$
