Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - 12x^{2} - 8x + 72 \)
|
The roots of $f$ are computed in $\Q_{ 23 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 9 + 10\cdot 23 + 18\cdot 23^{2} + 5\cdot 23^{3} + 21\cdot 23^{4} +O(23^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 18 + 8\cdot 23 + 12\cdot 23^{2} + 22\cdot 23^{3} + 17\cdot 23^{4} +O(23^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 20 + 9\cdot 23 + 14\cdot 23^{2} + 8\cdot 23^{3} + 3\cdot 23^{4} +O(23^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 22 + 16\cdot 23 + 9\cdot 23^{3} + 3\cdot 23^{4} +O(23^{5})\)
