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}
