Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 127 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 127 }$: $ x^{2} + 126 x + 3 $
Roots:
$r_{ 1 }$ $=$ $ 9 a + 23 + \left(81 a + 79\right)\cdot 127 + \left(124 a + 82\right)\cdot 127^{2} + \left(36 a + 40\right)\cdot 127^{3} + \left(3 a + 57\right)\cdot 127^{4} +O\left(127^{ 5 }\right)$

$r_{ 3 }$ $=$ $ 118 a + 32 + \left(45 a + 24\right)\cdot 127 + \left(2 a + 126\right)\cdot 127^{2} + \left(90 a + 79\right)\cdot 127^{3} + \left(123 a + 23\right)\cdot 127^{4} +O\left(127^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 34 a + 87 + \left(102 a + 3\right)\cdot 127 + \left(15 a + 2\right)\cdot 127^{2} + \left(109 a + 101\right)\cdot 127^{3} + \left(56 a + 45\right)\cdot 127^{4} +O\left(127^{ 5 }\right)$
