Defining polynomial
$f(x)$ | $=$ | \( x^{5} - x^{4} + 5x^{3} - x^{2} + 6x + 1 \) . |
The roots of $f$ are computed in $\Q_{ 137 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 19 + 60\cdot 137 + 117\cdot 137^{2} + 111\cdot 137^{3} + 42\cdot 137^{4} +O(137^{5})\) |
$r_{ 2 }$ | $=$ | \( 24 + 13\cdot 137 + 60\cdot 137^{2} + 118\cdot 137^{3} + 89\cdot 137^{4} +O(137^{5})\) |
$r_{ 3 }$ | $=$ | \( 74 + 9\cdot 137 + 52\cdot 137^{2} + 86\cdot 137^{3} + 25\cdot 137^{4} +O(137^{5})\) |
$r_{ 4 }$ | $=$ | \( 78 + 131\cdot 137 + 16\cdot 137^{2} + 132\cdot 137^{3} + 40\cdot 137^{4} +O(137^{5})\) |
$r_{ 5 }$ | $=$ | \( 80 + 59\cdot 137 + 27\cdot 137^{2} + 99\cdot 137^{3} + 74\cdot 137^{4} +O(137^{5})\) |
