Defining polynomial
$f(x)$ | $=$ | \( x^{4} - x^{3} + 127x^{2} + 2849x + 26983 \) . |
The roots of $f$ are computed in $\Q_{ 19 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ |
\( 3 + 4\cdot 19 + 6\cdot 19^{2} + 19^{4} +O(19^{5})\)
$r_{ 2 }$ |
$=$ |
\( 4 + 15\cdot 19 + 14\cdot 19^{2} + 18\cdot 19^{3} +O(19^{5})\)
| $r_{ 3 }$ |
$=$ |
\( 14 + 10\cdot 19^{2} + 19^{3} + 12\cdot 19^{4} +O(19^{5})\)
| $r_{ 4 }$ |
$=$ |
\( 18 + 17\cdot 19 + 6\cdot 19^{2} + 17\cdot 19^{3} + 4\cdot 19^{4} +O(19^{5})\)
