Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - 2x^{3} + 2x^{2} - 2 \)
|
The roots of $f$ are computed in $\Q_{ 223 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 21 + 203\cdot 223 + 74\cdot 223^{2} + 170\cdot 223^{3} + 59\cdot 223^{4} +O(223^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 133 + 78\cdot 223 + 80\cdot 223^{2} + 153\cdot 223^{3} + 93\cdot 223^{4} +O(223^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 137 + 212\cdot 223 + 187\cdot 223^{2} + 167\cdot 223^{3} + 195\cdot 223^{4} +O(223^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 157 + 174\cdot 223 + 102\cdot 223^{2} + 177\cdot 223^{3} + 96\cdot 223^{4} +O(223^{5})\)
