Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} + x - 2 \)

The roots of $f$ are computed in $\Q_{ 37 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 12 + 13\cdot 37 + 7\cdot 37^{2} + 2\cdot 37^{3} +O(37^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 18 + 27\cdot 37 + 35\cdot 37^{3} + 27\cdot 37^{4} +O(37^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 22 + 29\cdot 37 + 11\cdot 37^{2} + 26\cdot 37^{3} + 25\cdot 37^{4} +O(37^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 23 + 3\cdot 37 + 17\cdot 37^{2} + 10\cdot 37^{3} + 20\cdot 37^{4} +O(37^{5})\)
