Defining polynomial
$f(x)$ | $=$ | \( x^{5} - x^{4} - 4x^{3} + 3x^{2} + 3x - 1 \) . |
The roots of $f$ are computed in $\Q_{ 23 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 9 + 20\cdot 23 + 11\cdot 23^{2} + 6\cdot 23^{3} + 11\cdot 23^{4} +O(23^{5})\) |
$r_{ 2 }$ | $=$ | \( 12 + 11\cdot 23^{2} + 17\cdot 23^{3} + 20\cdot 23^{4} +O(23^{5})\) |
$r_{ 3 }$ | $=$ | \( 13 + 4\cdot 23 + 7\cdot 23^{2} + 14\cdot 23^{4} +O(23^{5})\) |
$r_{ 4 }$ | $=$ | \( 17 + 3\cdot 23 + 4\cdot 23^{2} + 4\cdot 23^{3} + 21\cdot 23^{4} +O(23^{5})\) |
$r_{ 5 }$ | $=$ | \( 19 + 16\cdot 23 + 11\cdot 23^{2} + 17\cdot 23^{3} + 23^{4} +O(23^{5})\) |
