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:
$r_{ 1 }$ $=$ $ 11 a + 5 + \left(8 a + 14\right)\cdot 17 + \left(13 a + 12\right)\cdot 17^{2} + \left(8 a + 7\right)\cdot 17^{3} + \left(a + 11\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 4 a + 3 + \left(6 a + 5\right)\cdot 17 + \left(16 a + 6\right)\cdot 17^{2} + \left(13 a + 5\right)\cdot 17^{3} + \left(3 a + 3\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 10 a + 5 + \left(14 a + 12\right)\cdot 17 + \left(2 a + 4\right)\cdot 17^{2} + \left(5 a + 6\right)\cdot 17^{3} + \left(2 a + 12\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 7 a + 15 + \left(2 a + 16\right)\cdot 17 + \left(14 a + 9\right)\cdot 17^{2} + \left(11 a + 8\right)\cdot 17^{3} + \left(14 a + 9\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 13 a + 7 + \left(10 a + 7\right)\cdot 17 + 16\cdot 17^{2} + \left(3 a + 2\right)\cdot 17^{3} + \left(13 a + 10\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 6 a + 16 + \left(8 a + 11\right)\cdot 17 + 3 a\cdot 17^{2} + \left(8 a + 3\right)\cdot 17^{3} + \left(15 a + 4\right)\cdot 17^{4} +O\left(17^{ 5 }\right)$
