Defining polynomial
| $f(x)$ | $=$ |
\( x^{3} - x^{2} + 13x + 7 \)
|
The roots of $f$ are computed in $\Q_{ 17 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 10 + 6\cdot 17 + 14\cdot 17^{2} + 15\cdot 17^{3} + 16\cdot 17^{4} +O(17^{5})\)
| $r_{ 2 }$ |
$=$ |
\( 11 + 4\cdot 17 + 13\cdot 17^{2} + 3\cdot 17^{3} + 14\cdot 17^{4} +O(17^{5})\)
| $r_{ 3 }$ |
$=$ |
\( 14 + 5\cdot 17 + 6\cdot 17^{2} + 14\cdot 17^{3} + 2\cdot 17^{4} +O(17^{5})\)
