Defining polynomial
$f(x)$ | $=$ | \( x^{3} - x^{2} - 3 \) . |
The roots of $f$ are computed in $\Q_{ 71 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ |
\( 11 + 57\cdot 71 + 71^{2} + 43\cdot 71^{3} + 19\cdot 71^{4} +O(71^{5})\)
$r_{ 2 }$ |
$=$ |
\( 20 + 34\cdot 71 + 43\cdot 71^{2} + 18\cdot 71^{3} + 46\cdot 71^{4} +O(71^{5})\)
| $r_{ 3 }$ |
$=$ |
\( 41 + 50\cdot 71 + 25\cdot 71^{2} + 9\cdot 71^{3} + 5\cdot 71^{4} +O(71^{5})\)
