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

The roots of $f$ are computed in $\Q_{ 71 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 7 + 50\cdot 71 + 11\cdot 71^{2} + 54\cdot 71^{3} + 50\cdot 71^{4} +O(71^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 21 + 38\cdot 71 + 66\cdot 71^{2} + 42\cdot 71^{3} + 49\cdot 71^{4} +O(71^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 43 + 53\cdot 71 + 63\cdot 71^{2} + 44\cdot 71^{3} + 41\cdot 71^{4} +O(71^{5})\)
