Defining polynomial
| $f(x)$ | $=$ |
\( x^{4} - x^{3} + x^{2} - 2x + 2 \)
|
The roots of $f$ are computed in $\Q_{ 173 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 48 + 75\cdot 173 + 91\cdot 173^{2} + 119\cdot 173^{3} + 156\cdot 173^{4} +O(173^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 57 + 15\cdot 173 + 94\cdot 173^{2} + 64\cdot 173^{3} + 143\cdot 173^{4} +O(173^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 73 + 28\cdot 173 + 88\cdot 173^{2} + 171\cdot 173^{3} + 2\cdot 173^{4} +O(173^{5})\)
|
| $r_{ 4 }$ | $=$ |
\( 169 + 53\cdot 173 + 72\cdot 173^{2} + 163\cdot 173^{3} + 42\cdot 173^{4} +O(173^{5})\)
