Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 17 }$ to precision 7.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 17 }$: $ x^{2} + 16 x + 3 $
Roots:
$r_{ 1 }$ $=$ $ 5 a + 5 + \left(8 a + 16\right)\cdot 17 + \left(13 a + 12\right)\cdot 17^{2} + \left(3 a + 11\right)\cdot 17^{3} + \left(2 a + 12\right)\cdot 17^{4} + \left(4 a + 10\right)\cdot 17^{5} + \left(16 a + 15\right)\cdot 17^{6} +O\left(17^{ 7 }\right)$
$r_{ 2 }$ $=$ $ 5 a + 7 + \left(8 a + 14\right)\cdot 17 + \left(13 a + 15\right)\cdot 17^{2} + \left(3 a + 14\right)\cdot 17^{3} + \left(2 a + 5\right)\cdot 17^{4} + \left(4 a + 4\right)\cdot 17^{5} + \left(16 a + 6\right)\cdot 17^{6} +O\left(17^{ 7 }\right)$
$r_{ 3 }$ $=$ $ 15 + 17 + 14\cdot 17^{2} + 13\cdot 17^{3} + 6\cdot 17^{4} + 6\cdot 17^{5} + 9\cdot 17^{6} +O\left(17^{ 7 }\right)$
$r_{ 4 }$ $=$ $ 12 a + 12 + 8 a\cdot 17 + \left(3 a + 4\right)\cdot 17^{2} + \left(13 a + 5\right)\cdot 17^{3} + \left(14 a + 4\right)\cdot 17^{4} + \left(12 a + 6\right)\cdot 17^{5} + 17^{6} +O\left(17^{ 7 }\right)$
