Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} - 24x^{2} - 22x + 29 \)
|
The roots of $f$ are computed in $\Q_{ 29 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 4\cdot 29 + 18\cdot 29^{2} + 22\cdot 29^{3} + 23\cdot 29^{4} +O(29^{5})\)
| $r_{ 2 }$ |
$=$ |
\( 10 + 5\cdot 29 + 11\cdot 29^{2} + 15\cdot 29^{3} + 16\cdot 29^{4} +O(29^{5})\)
| $r_{ 3 }$ |
$=$ |
\( 21 + 16\cdot 29 + 21\cdot 29^{2} + 23\cdot 29^{3} + 22\cdot 29^{4} +O(29^{5})\)
| $r_{ 4 }$ |
$=$ |
\( 28 + 2\cdot 29 + 7\cdot 29^{2} + 25\cdot 29^{3} + 23\cdot 29^{4} +O(29^{5})\)
