Defining polynomial

$f(x)$$=$\(x^{3} - 2 x - 2\)  Toggle raw display.

The roots of $f$ are computed in $\Q_{ 23 }$ to precision 5.

Roots:
$r_{ 1 }$ $=$ \( 12 + 4\cdot 23 + 8\cdot 23^{2} + 22\cdot 23^{3} + 10\cdot 23^{4} +O(23^{5})\)  Toggle raw display
$r_{ 2 }$ $=$ \( 14 + 6\cdot 23 + 5\cdot 23^{2} + 7\cdot 23^{3} + 15\cdot 23^{4} +O(23^{5})\)  Toggle raw display
$r_{ 3 }$ $=$ \( 20 + 11\cdot 23 + 9\cdot 23^{2} + 16\cdot 23^{3} + 19\cdot 23^{4} +O(23^{5})\)  Toggle raw display
