Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - 2x^{3} - 2x^{2} + 6 \)
|
The roots of $f$ are computed in $\Q_{ 149 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 26 + 111\cdot 149 + 117\cdot 149^{2} + 80\cdot 149^{3} + 49\cdot 149^{4} +O(149^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 63 + 28\cdot 149 + 62\cdot 149^{2} + 88\cdot 149^{3} + 83\cdot 149^{4} +O(149^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 95 + 50\cdot 149 + 117\cdot 149^{2} + 130\cdot 149^{3} + 23\cdot 149^{4} +O(149^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 116 + 107\cdot 149 + 147\cdot 149^{3} + 140\cdot 149^{4} +O(149^{5})\)
