Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} + 2x^{2} + 2 \)
|
The roots of $f$ are computed in $\Q_{ 229 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 34 + 159\cdot 229 + 67\cdot 229^{2} + 206\cdot 229^{3} + 32\cdot 229^{4} +O(229^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 64 + 155\cdot 229 + 73\cdot 229^{2} + 162\cdot 229^{3} + 92\cdot 229^{4} +O(229^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 65 + 160\cdot 229 + 52\cdot 229^{2} + 60\cdot 229^{3} + 66\cdot 229^{4} +O(229^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 67 + 212\cdot 229 + 34\cdot 229^{2} + 29\cdot 229^{3} + 37\cdot 229^{4} +O(229^{5})\)
