Defining polynomial
$f(x)$ | $=$ | \( x^{5} - x^{4} - 4x^{3} - 8x^{2} + 25x - 1 \) . |
The roots of $f$ are computed in $\Q_{ 449 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 107 + 396\cdot 449 + 197\cdot 449^{2} + 434\cdot 449^{3} + 397\cdot 449^{4} +O(449^{5})\) |
$r_{ 2 }$ | $=$ | \( 133 + 215\cdot 449 + 174\cdot 449^{2} + 346\cdot 449^{3} + 332\cdot 449^{4} +O(449^{5})\) |
$r_{ 3 }$ | $=$ | \( 140 + 24\cdot 449 + 378\cdot 449^{2} + 324\cdot 449^{3} + 233\cdot 449^{4} +O(449^{5})\) |
$r_{ 4 }$ | $=$ | \( 190 + 17\cdot 449 + 398\cdot 449^{2} + 425\cdot 449^{3} + 262\cdot 449^{4} +O(449^{5})\) |
$r_{ 5 }$ | $=$ | \( 329 + 244\cdot 449 + 198\cdot 449^{2} + 264\cdot 449^{3} + 119\cdot 449^{4} +O(449^{5})\) |
