Question

Me ajudem x²-xy/xy+y÷xy-y²/x²+x

Answer 1

$\frac{ \frac{x^{2}-xy }{xy+y}}{ \frac{xy-y^{2}}{ x^{2} +x} } =$

$\frac{ x^{2} -xy}{xy+y}* \frac{ x^{2}+x }{xy- y^{2}} =$

$\frac{ x^{4}- x^{3}y + x^{3}- x^{2}y}{ x^{2} y^{2}+x y^{2}- y^{3}-xy^{3}} =$

$\frac{x^{2} ( x^{2} -xy+x-y)}{y^{2}( x^{2} +x-y-xy)} =$

$\frac{x^{2} }{y^{2} } =$
