Defining polynomial
$f(x)$ | $=$ | \( x^{5} - x^{4} + 5x^{3} + 11x^{2} + 4x - 1 \) . |
The roots of $f$ are computed in $\Q_{ 241 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 47 + 194\cdot 241 + 5\cdot 241^{2} + 200\cdot 241^{3} + 188\cdot 241^{4} +O(241^{5})\) |
$r_{ 2 }$ | $=$ | \( 88 + 84\cdot 241 + 45\cdot 241^{2} + 31\cdot 241^{3} + 45\cdot 241^{4} +O(241^{5})\) |
$r_{ 3 }$ | $=$ | \( 175 + 27\cdot 241 + 12\cdot 241^{2} + 65\cdot 241^{3} + 218\cdot 241^{4} +O(241^{5})\) |
$r_{ 4 }$ | $=$ | \( 188 + 88\cdot 241 + 233\cdot 241^{2} + 186\cdot 241^{3} + 5\cdot 241^{4} +O(241^{5})\) |
$r_{ 5 }$ | $=$ | \( 226 + 86\cdot 241 + 185\cdot 241^{2} + 239\cdot 241^{3} + 23\cdot 241^{4} +O(241^{5})\) |
