Defining polynomial

$f(x)$$=$ \( x^{4} - 2x^{3} + 3x^{2} - 1 \) Copy content Toggle raw display .

The roots of $f$ are computed in $\Q_{ 43 }$ to precision 5.

Roots:
$r_{ 1 }$ $=$ \( 10 + 14\cdot 43 + 25\cdot 43^{2} + 12\cdot 43^{3} + 25\cdot 43^{4} +O(43^{5})\) Copy content Toggle raw display
$r_{ 2 }$ $=$ \( 11 + 5\cdot 43 + 21\cdot 43^{2} + 21\cdot 43^{3} + 28\cdot 43^{4} +O(43^{5})\) Copy content Toggle raw display
$r_{ 3 }$ $=$ \( 26 + 35\cdot 43 + 20\cdot 43^{2} + 31\cdot 43^{3} + 37\cdot 43^{4} +O(43^{5})\) Copy content Toggle raw display
$r_{ 4 }$ $=$ \( 41 + 30\cdot 43 + 18\cdot 43^{2} + 20\cdot 43^{3} + 37\cdot 43^{4} +O(43^{5})\) Copy content Toggle raw display
