Answer 2

Step-by-step explanation:

$a + \frac{1}{a} = \frac{17}{4} \\ {a}^{2} + \frac{1}{ {a}^{2} } + 2 = \frac{289}{16} \\ {a}^{2} + \frac{1}{ {a}^{2} } = \frac{257}{16} \\ ( {a - \frac{1}{a} )}^{2} + 2 = \frac{257}{16} \\ ( {a - \frac{1}{a} )}^{2} = \frac{225}{16} \\ a - \frac{1}{a} = \frac{15}{4} \\ \\ hope \: it \: will \: help \: you \:$
