Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 293 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 293 }$: $ x^{2} + 292 x + 2 $
Roots:
$r_{ 1 }$ $=$ $ 208 a + 94 + \left(264 a + 111\right)\cdot 293 + \left(139 a + 118\right)\cdot 293^{2} + \left(22 a + 221\right)\cdot 293^{3} + \left(192 a + 127\right)\cdot 293^{4} +O\left(293^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 85 a + 9 + \left(28 a + 168\right)\cdot 293 + \left(153 a + 286\right)\cdot 293^{2} + \left(270 a + 103\right)\cdot 293^{3} + \left(100 a + 4\right)\cdot 293^{4} +O\left(293^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 115 + 50\cdot 293 + 27\cdot 293^{2} + 166\cdot 293^{3} + 284\cdot 293^{4} +O\left(293^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 137 a + 152 + \left(282 a + 250\right)\cdot 293 + \left(107 a + 10\right)\cdot 293^{2} + \left(235 a + 185\right)\cdot 293^{3} + \left(88 a + 85\right)\cdot 293^{4} +O\left(293^{ 5 }\right)$
