Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 31 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 31 }$: $ x^{2} + 29 x + 3 $
Roots:
$r_{ 1 }$ $=$ $ 9 a + 19 + \left(14 a + 8\right)\cdot 31 + \left(17 a + 2\right)\cdot 31^{2} + \left(25 a + 4\right)\cdot 31^{3} + \left(23 a + 25\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 6 a + 21 + \left(23 a + 13\right)\cdot 31 + \left(18 a + 21\right)\cdot 31^{2} + \left(26 a + 15\right)\cdot 31^{3} + \left(25 a + 21\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 25 a + 2 + \left(7 a + 23\right)\cdot 31 + \left(12 a + 4\right)\cdot 31^{2} + \left(4 a + 19\right)\cdot 31^{3} + \left(5 a + 15\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 11 a + 27 + \left(9 a + 5\right)\cdot 31 + \left(14 a + 11\right)\cdot 31^{2} + \left(20 a + 10\right)\cdot 31^{3} + \left(28 a + 4\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 22 a + 6 + \left(16 a + 28\right)\cdot 31 + \left(13 a + 22\right)\cdot 31^{2} + \left(5 a + 6\right)\cdot 31^{3} + \left(7 a + 16\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 20 a + 18 + \left(21 a + 13\right)\cdot 31 + \left(16 a + 30\right)\cdot 31^{2} + \left(10 a + 5\right)\cdot 31^{3} + \left(2 a + 10\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$
