Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - 2x^{3} - 3x^{2} + 2x + 3 \)
|
The roots of $f$ are computed in $\Q_{ 223 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 8 + 168\cdot 223 + 68\cdot 223^{2} + 132\cdot 223^{3} + 120\cdot 223^{4} +O(223^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 89 + 173\cdot 223 + 179\cdot 223^{2} + 115\cdot 223^{3} + 150\cdot 223^{4} +O(223^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 175 + 14\cdot 223 + 145\cdot 223^{2} + 169\cdot 223^{3} + 60\cdot 223^{4} +O(223^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 176 + 89\cdot 223 + 52\cdot 223^{2} + 28\cdot 223^{3} + 114\cdot 223^{4} +O(223^{5})\)
