Question

show that
$\frac{ {x}^{ - 1} + {y}^{ - 1} }{ {x}^{ - 1} } + \frac{ {x}^{ - 1} - {y}^{ - 1} }{ {x}^{ - 1} } = \frac{ {x}^{2} + {y}^{2} }{xy}$

Answer 1

Hey Friend,

There is a correction in your question. The actual question is: 

$\frac{{x}^{-1}+{y}^{-1}}{{x}^{-1}}+\frac{{x}^{-1}-{y}^{-1}}{{y}^{-1}}=\frac{{x}^{2}+{y}^{2}}{xy}$


The correction and the solution both are as shown in the image.

Hope it helps,
