Defining polynomial

$f(x)$$=$ \( x^{3} - 21x - 28 \) Copy content Toggle raw display .

The roots of $f$ are computed in $\Q_{ 31 }$ to precision 5.

Roots:
$r_{ 1 }$ $=$ \( 2 + 17\cdot 31 + 13\cdot 31^{2} + 30\cdot 31^{3} + 15\cdot 31^{4} +O(31^{5})\) Copy content Toggle raw display
$r_{ 2 }$ $=$ \( 6 + 21\cdot 31 + 5\cdot 31^{2} + 23\cdot 31^{3} + 9\cdot 31^{4} +O(31^{5})\) Copy content Toggle raw display
$r_{ 3 }$ $=$ \( 23 + 23\cdot 31 + 11\cdot 31^{2} + 8\cdot 31^{3} + 5\cdot 31^{4} +O(31^{5})\) Copy content Toggle raw display
