Answer 1

Answer:-

$\implies \: \frac{a + xi}{a - xi} + \frac{a - xi}{a + xi} \\ \\ \implies \: \frac{ {(a + xi)}^{2} + {(a - xi)}^{2} }{(a + xi)(a - xi)} \\ \\ \implies \: \frac{ {a}^{2} + {x}^{2} {i}^{2} + 2axi + {a}^{2} + {x}^{2} {i}^{2} - 2axi }{ {a}^{2} - {x}^{2} {i}^{2} } \\ \because \: {i}^{2} = - 1 \\ \\ \implies \: \frac{ {a}^{2} - {x}^{2} + {a}^{2} - {x}^{2} }{ {a}^{2} + {x}^{2} } \\ \\ \implies \: \frac{2 {a}^{2} - 2 {x}^{2} }{ {a}^{2} + {x}^{2} }$
