Defining polynomial
$f(x)$ | $=$ | \( x^{3} - x^{2} - 6x + 1 \) . |
The roots of $f$ are computed in $\Q_{ 17 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ |
\( 9 + 9\cdot 17 + 7\cdot 17^{2} + 5\cdot 17^{3} + 9\cdot 17^{4} +O(17^{5})\)
$r_{ 2 }$ |
$=$ |
\( 12 + 12\cdot 17 + 7\cdot 17^{2} + 2\cdot 17^{3} + 17^{4} +O(17^{5})\)
| $r_{ 3 }$ |
$=$ |
\( 14 + 11\cdot 17 + 17^{2} + 9\cdot 17^{3} + 6\cdot 17^{4} +O(17^{5})\)
