Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 11 }$ to precision 7.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 11 }$:
\( x^{2} + 7x + 2 \)
Roots:
$r_{ 1 }$ | $=$ |

$r_{ 2 }$ |
$=$ |
\( 3 a + 8 + \left(6 a + 8\right)\cdot 11 + \left(9 a + 8\right)\cdot 11^{2} + \left(4 a + 9\right)\cdot 11^{3} + 6 a\cdot 11^{4} + \left(2 a + 6\right)\cdot 11^{5} + \left(2 a + 3\right)\cdot 11^{6} +O(11^{7})\)
