Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} + 5x^{2} - 6x + 7 \)
|
The roots of $f$ are computed in $\Q_{ 43 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 5 + 25\cdot 43 + 24\cdot 43^{2} + 28\cdot 43^{3} + 3\cdot 43^{4} +O(43^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 18 + 31\cdot 43 + 43^{2} + 22\cdot 43^{3} + 37\cdot 43^{4} +O(43^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 31 + 22\cdot 43 + 18\cdot 43^{2} + 40\cdot 43^{3} + 21\cdot 43^{4} +O(43^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 33 + 6\cdot 43 + 41\cdot 43^{2} + 37\cdot 43^{3} + 22\cdot 43^{4} +O(43^{5})\)
