Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} + 22x^{2} + x + 1 \)
|
The roots of $f$ are computed in $\Q_{ 37 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 10 + 27\cdot 37 + 11\cdot 37^{2} + 33\cdot 37^{3} + 19\cdot 37^{4} +O(37^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 11 + 7\cdot 37 + 5\cdot 37^{2} + 34\cdot 37^{3} + 19\cdot 37^{4} +O(37^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 19 + 34\cdot 37^{2} + 10\cdot 37^{3} + 9\cdot 37^{4} +O(37^{5})\)
