Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} + 7x^{2} - 2x + 14 \)
|
The roots of $f$ are computed in $\Q_{ 151 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 60 + 26\cdot 151 + 95\cdot 151^{2} + 134\cdot 151^{3} + 112\cdot 151^{4} +O(151^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 62 + 80\cdot 151 + 36\cdot 151^{2} + 92\cdot 151^{3} + 81\cdot 151^{4} +O(151^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 80 + 24\cdot 151 + 148\cdot 151^{2} + 86\cdot 151^{3} + 107\cdot 151^{4} +O(151^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 100 + 19\cdot 151 + 22\cdot 151^{2} + 139\cdot 151^{3} + 150\cdot 151^{4} +O(151^{5})\)
