Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} - x^{2} + 2x + 2 \)
|
The roots of $f$ are computed in $\Q_{ 337 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 71 + 40\cdot 337 + 266\cdot 337^{2} + 28\cdot 337^{3} + 56\cdot 337^{4} +O(337^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 75 + 230\cdot 337 + 185\cdot 337^{2} + 211\cdot 337^{3} + 46\cdot 337^{4} +O(337^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 235 + 217\cdot 337 + 15\cdot 337^{2} + 215\cdot 337^{3} + 96\cdot 337^{4} +O(337^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 294 + 185\cdot 337 + 206\cdot 337^{2} + 218\cdot 337^{3} + 137\cdot 337^{4} +O(337^{5})\)
