Defining polynomial
| $f(x)$ | $=$ |
\( x^{3} - x^{2} - 24x + 27 \)
|
The roots of $f$ are computed in $\Q_{ 7 }$ to precision 5.
Roots:
| $r_{ 1 }$ | $=$ |
\( 4 + 5\cdot 7 + 4\cdot 7^{2} + 4\cdot 7^{3} + 7^{4} +O(7^{5})\)
|
| $r_{ 2 }$ | $=$ |
\( 5 + 7 + 6\cdot 7^{2} + 4\cdot 7^{3} + 7^{4} +O(7^{5})\)
|
| $r_{ 3 }$ | $=$ |
\( 6 + 6\cdot 7 + 2\cdot 7^{2} + 4\cdot 7^{3} + 3\cdot 7^{4} +O(7^{5})\)
