Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} - 3x^{2} + 4x - 3 \)
|
The roots of $f$ are computed in $\Q_{ 211 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 35 + 48\cdot 211 + 143\cdot 211^{2} + 120\cdot 211^{3} + 193\cdot 211^{4} +O(211^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 95 + 71\cdot 211 + 147\cdot 211^{2} + 111\cdot 211^{3} + 50\cdot 211^{4} +O(211^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 145 + 46\cdot 211 + 196\cdot 211^{2} + 7\cdot 211^{3} + 141\cdot 211^{4} +O(211^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 148 + 44\cdot 211 + 146\cdot 211^{2} + 181\cdot 211^{3} + 36\cdot 211^{4} +O(211^{5})\)
