Defining polynomial
$f(x)$ | $=$ | \( x^{3} - x^{2} - 30x + 64 \) . |
The roots of $f$ are computed in $\Q_{ 17 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 1 + 3\cdot 17 + 11\cdot 17^{2} + 16\cdot 17^{3} + 14\cdot 17^{4} +O(17^{5})\) |
$r_{ 2 }$ | $=$ | \( 8 + 12\cdot 17 + 12\cdot 17^{2} + 15\cdot 17^{3} + 13\cdot 17^{4} +O(17^{5})\) |
$r_{ 3 }$ | $=$ | \( 9 + 17 + 10\cdot 17^{2} + 17^{3} + 5\cdot 17^{4} +O(17^{5})\) |
