Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} - x^{2} + 6x - 7 \)
|
The roots of $f$ are computed in $\Q_{ 223 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 9 + 195\cdot 223 + 39\cdot 223^{2} + 170\cdot 223^{3} + 46\cdot 223^{4} +O(223^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 55 + 163\cdot 223 + 183\cdot 223^{2} + 5\cdot 223^{3} + 112\cdot 223^{4} +O(223^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 180 + 137\cdot 223 + 175\cdot 223^{2} + 63\cdot 223^{3} + 79\cdot 223^{4} +O(223^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 203 + 172\cdot 223 + 46\cdot 223^{2} + 206\cdot 223^{3} + 207\cdot 223^{4} +O(223^{5})\)
