Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} - 49x^{2} + 49x + 451 \)
|
The roots of $f$ are computed in $\Q_{ 11 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 5\cdot 11 + 5\cdot 11^{3} + 4\cdot 11^{4} +O(11^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 1 + 2\cdot 11 + 5\cdot 11^{2} + 7\cdot 11^{4} +O(11^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 4 + 9\cdot 11 + 10\cdot 11^{2} + 8\cdot 11^{3} +O(11^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 7 + 5\cdot 11 + 5\cdot 11^{2} + 7\cdot 11^{3} + 9\cdot 11^{4} +O(11^{5})\)
