Question

please simplify this question​

Answer 1

${(a - \frac{1}{a} ) }^{2} +{ (a + \frac{1}{a} ) }^{2} \\ \\ {a}^{2} - 2.a. \frac{1}{a} + \frac{1}{ {a}^{2} } + {a}^{2} + \frac{1}{ {a}^{2} } + 2.a. \frac{1}{a} \\ \\ 2{a}^{2} + \frac{2}{ {a}^{2} } - 2 + 2 = 0 \\ \\ 2( {a}^{2} + \frac{1}{ {a}^{2} } )$
