Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 269 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ \( 52 + 39\cdot 269 + 148\cdot 269^{2} + 164\cdot 269^{3} + 60\cdot 269^{4} +O(269^{5})\)  Toggle raw display
$r_{ 2 }$ $=$ \( 60 + 178\cdot 269 + 199\cdot 269^{2} + 152\cdot 269^{3} + 180\cdot 269^{4} +O(269^{5})\)  Toggle raw display
