Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{2} - x + 2 \)
|
The roots of $f$ are computed in $\Q_{ 101 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 13 + 38\cdot 101 + 41\cdot 101^{2} + 56\cdot 101^{3} + 43\cdot 101^{4} +O(101^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 18 + 36\cdot 101 + 36\cdot 101^{2} + 24\cdot 101^{3} + 32\cdot 101^{4} +O(101^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 21 + 49\cdot 101 + 56\cdot 101^{2} + 36\cdot 101^{3} + 18\cdot 101^{4} +O(101^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 49 + 78\cdot 101 + 67\cdot 101^{2} + 84\cdot 101^{3} + 6\cdot 101^{4} +O(101^{5})\)
