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 $\mathbb{Q}_{ 17 }$: \(x^{2} + 16 x + 3\)  Toggle raw display
Roots:
$r_{ 1 }$ $=$ \( 8 a + 7 + \left(3 a + 11\right)\cdot 17 + \left(3 a + 4\right)\cdot 17^{2} + \left(16 a + 1\right)\cdot 17^{3} + \left(15 a + 10\right)\cdot 17^{4} +O(17^{5})\)  Toggle raw display
$r_{ 2 }$ $=$ \( 5 + 17 + 9\cdot 17^{2} + 15\cdot 17^{3} + 2\cdot 17^{4} +O(17^{5})\)  Toggle raw display
$r_{ 3 }$ $=$ \( 9 a + 15 + \left(13 a + 6\right)\cdot 17 + \left(13 a + 4\right)\cdot 17^{2} + 14\cdot 17^{3} + \left(a + 9\right)\cdot 17^{4} +O(17^{5})\)  Toggle raw display
