Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} - 31x^{2} - 28x + 435 \)
|
The roots of $f$ are computed in $\Q_{ 29 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 14\cdot 29 + 28\cdot 29^{2} + 25\cdot 29^{3} + 19\cdot 29^{4} +O(29^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 11 + 23\cdot 29 + 18\cdot 29^{2} + 13\cdot 29^{3} + 29^{4} +O(29^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 22 + 18\cdot 29 + 27\cdot 29^{2} + 8\cdot 29^{3} + 9\cdot 29^{4} +O(29^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 26 + 29 + 12\cdot 29^{2} + 9\cdot 29^{3} + 27\cdot 29^{4} +O(29^{5})\)
