Answer:

$\huge\underline{ \underline{ \red{your \: \: answer}}}$

Step-by-step explanation:

$\sf\red{ {a}^{2} - 3a + 1 } \\ \sf\red{using \: quadratic \: equation \frac{ - b±\sqrt{ {b}^{2} - 4ac } }{2a} } \\ \sf\pink{ = > \frac{ - ( - 3)± \sqrt{ { - 3}^{2} - 4 \times 1 \times 1} }{2 \times 1} } \\ \sf\blue{ = > \frac{3± \sqrt{9 - 4} }{2} } \\ \sf\orange{ = > \frac{3±\sqrt{5} }{2} } \\ \sf\green{a = \frac{3 - \sqrt{5} }{2} \: and \: \frac{3 + \sqrt{5} }{2} } \\ \sf\red{a + \frac{1}{a} = ?} \\ \sf\purple{ = > \frac{3 + \sqrt{5} }{2} + \frac{1}{( \frac{3 + \sqrt{5} }{2} )} } \\ \sf\pink{ = > \frac{3 + \sqrt{5} }{2} + \frac{2}{3 + \sqrt{5} } } \\ \sf\orange{ = > \frac{ {(3 + \sqrt{5} )}^{2} + {2}^{2} }{2(3 + \sqrt{5} )} } \\ \sf\green{ = > \frac{18 + 6 \sqrt{5} }{2(3 + \sqrt{5} )} } \\ \sf\red{ = > \frac{6(3 + \sqrt{5}) }{2(3 + \sqrt{5} )}} \\ \sf\blue{ = > \frac{6}{2} } \\ \sf\pink{ = > 3}$
