Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} - 3x^{2} + 2 \)
|
The roots of $f$ are computed in $\Q_{ 211 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 47 + 116\cdot 211 + 174\cdot 211^{2} + 132\cdot 211^{3} + 108\cdot 211^{4} +O(211^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 116 + 76\cdot 211 + 193\cdot 211^{2} + 57\cdot 211^{3} + 100\cdot 211^{4} +O(211^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 117 + 168\cdot 211 + 14\cdot 211^{2} + 66\cdot 211^{3} + 2\cdot 211^{4} +O(211^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 143 + 60\cdot 211 + 39\cdot 211^{2} + 165\cdot 211^{3} + 210\cdot 211^{4} +O(211^{5})\)
