Defining polynomial
| $f(x)$ | $=$ |
\( x^{3} - x^{2} + 2x + 1 \)
|
The roots of $f$ are computed in $\Q_{ 41 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 22 + 28\cdot 41 + 37\cdot 41^{2} + 2\cdot 41^{3} + 3\cdot 41^{4} +O(41^{5})\)
| $r_{ 2 }$ |
$=$ |
\( 23 + 19\cdot 41 + 31\cdot 41^{2} + 37\cdot 41^{3} + 41^{4} +O(41^{5})\)
| $r_{ 3 }$ |
$=$ |
\( 38 + 33\cdot 41 + 12\cdot 41^{2} + 36\cdot 41^{4} +O(41^{5})\)
