Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} + 3x^{2} + 2 \)
|
The roots of $f$ are computed in $\Q_{ 103 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 9 + 3\cdot 103 + 6\cdot 103^{2} + 45\cdot 103^{3} + 5\cdot 103^{4} +O(103^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 25 + 51\cdot 103 + 22\cdot 103^{2} + 10\cdot 103^{3} + 21\cdot 103^{4} +O(103^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 31 + 6\cdot 103 + 14\cdot 103^{2} + 97\cdot 103^{3} + 49\cdot 103^{4} +O(103^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 39 + 42\cdot 103 + 60\cdot 103^{2} + 53\cdot 103^{3} + 26\cdot 103^{4} +O(103^{5})\)
