Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 17 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 17 }$: $ x^{2} + 16 x + 3 $
Roots:

$=$ |

| $r_{ 2 }$ |
$=$ |
$ 15 a + 14 + \left(3 a + 10\right)\cdot 17 + \left(16 a + 7\right)\cdot 17^{2} + \left(10 a + 4\right)\cdot 17^{3} + \left(16 a + 9\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$ |
