Defining polynomial
$f(x)$ | $=$ | \( x^{4} - x^{3} + 6x^{2} + 11x + 10 \) . |
The roots of $f$ are computed in $\Q_{ 19 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 4 + 19 + 9\cdot 19^{2} + 19^{4} +O(19^{5})\) |
$r_{ 2 }$ | $=$ | \( 8 + 15\cdot 19 + 2\cdot 19^{2} + 19^{3} + 16\cdot 19^{4} +O(19^{5})\) |
$r_{ 3 }$ | $=$ | \( 13 + 17\cdot 19 + 19^{2} + 16\cdot 19^{3} + 5\cdot 19^{4} +O(19^{5})\) |
$r_{ 4 }$ | $=$ | \( 14 + 3\cdot 19 + 5\cdot 19^{2} + 19^{3} + 15\cdot 19^{4} +O(19^{5})\) |
