Defining polynomial
$f(x)$ | $=$ | \( x^{4} - x^{3} + 7x^{2} + 43x + 47 \) . |
The roots of $f$ are computed in $\Q_{ 47 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 12\cdot 47 + 8\cdot 47^{2} + 17\cdot 47^{3} + 25\cdot 47^{4} +O(47^{5})\) |
$r_{ 2 }$ | $=$ | \( 13 + 35\cdot 47 + 34\cdot 47^{2} + 5\cdot 47^{3} + 28\cdot 47^{4} +O(47^{5})\) |
$r_{ 3 }$ | $=$ | \( 16 + 15\cdot 47 + 6\cdot 47^{2} + 3\cdot 47^{3} + 9\cdot 47^{4} +O(47^{5})\) |
$r_{ 4 }$ | $=$ | \( 19 + 31\cdot 47 + 44\cdot 47^{2} + 20\cdot 47^{3} + 31\cdot 47^{4} +O(47^{5})\) |
