Defining polynomial

$f(x)$$=$\(x^{3} - x^{2} - 6 x + 7\)  Toggle raw display.

The roots of $f$ are computed in $\Q_{ 7 }$ to precision 5.

Roots:
$r_{ 1 }$ $=$ \( 6\cdot 7 + 6\cdot 7^{2} + 6\cdot 7^{4} +O(7^{5})\)  Toggle raw display
$r_{ 2 }$ $=$ \( 3 + 6\cdot 7 + 5\cdot 7^{4} +O(7^{5})\)  Toggle raw display
$r_{ 3 }$ $=$ \( 5 + 7 + 6\cdot 7^{2} + 5\cdot 7^{3} + 2\cdot 7^{4} +O(7^{5})\)  Toggle raw display
