Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} + x^{2} + x - 1 \)
|
The roots of $f$ are computed in $\Q_{ 113 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 40 + 35\cdot 113 + 41\cdot 113^{2} + 79\cdot 113^{3} + 67\cdot 113^{4} +O(113^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 94 + 58\cdot 113 + 20\cdot 113^{2} + 65\cdot 113^{3} + 55\cdot 113^{4} +O(113^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 96 + 64\cdot 113 + 113^{2} + 99\cdot 113^{3} + 91\cdot 113^{4} +O(113^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 110 + 66\cdot 113 + 49\cdot 113^{2} + 95\cdot 113^{3} + 10\cdot 113^{4} +O(113^{5})\)
