Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} + 2x^{2} - 3x + 2 \)
|
The roots of $f$ are computed in $\Q_{ 311 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 57 + 303\cdot 311 + 7\cdot 311^{2} + 99\cdot 311^{3} + 136\cdot 311^{4} +O(311^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 147 + 102\cdot 311 + 247\cdot 311^{2} + 14\cdot 311^{3} + 119\cdot 311^{4} +O(311^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 154 + 52\cdot 311 + 261\cdot 311^{2} + 143\cdot 311^{3} + 208\cdot 311^{4} +O(311^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 265 + 163\cdot 311 + 105\cdot 311^{2} + 53\cdot 311^{3} + 158\cdot 311^{4} +O(311^{5})\)
