Defining polynomial
| $f(x)$ | $=$ |
\( x^{3} - x^{2} - 6x + 3 \)

The roots of $f$ are computed in $\Q_{ 31 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 8 + 26\cdot 31 + 10\cdot 31^{2} + 23\cdot 31^{3} + 8\cdot 31^{4} +O(31^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 11 + 31 + 28\cdot 31^{2} + 24\cdot 31^{3} + 16\cdot 31^{4} +O(31^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 13 + 3\cdot 31 + 23\cdot 31^{2} + 13\cdot 31^{3} + 5\cdot 31^{4} +O(31^{5})\)
