Answer 1

Answer:

hope u understand the answer

Answer 2

Answer:

$\huge\green{\boxed{\sf Answer}}$

$( \frac{x}{y} + \frac{y}{x} )( \frac{x}{y} - \frac{y}{x} )$

Take LCM

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

Now Now multiple

$( \frac{x {}^{4} - y {}^{4} }{x {}^{2}y {}^{2} } )$

Here (a+b)(a-b)=a²-b² is the identity
