Defining polynomial
| $f(x)$ | $=$ |
\( x^{3} - 6x - 2 \)
|
The roots of $f$ are computed in $\Q_{ 67 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 10 + 51\cdot 67 + 31\cdot 67^{2} + 46\cdot 67^{3} + 27\cdot 67^{4} +O(67^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 15 + 49\cdot 67 + 62\cdot 67^{2} + 18\cdot 67^{3} + 22\cdot 67^{4} +O(67^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 42 + 33\cdot 67 + 39\cdot 67^{2} + 67^{3} + 17\cdot 67^{4} +O(67^{5})\)
