Defining polynomial
$f(x)$ | $=$ | \( x^{4} - 2x^{3} + 10x^{2} - 4x + 36 \) . |
The roots of $f$ are computed in $\Q_{ 47 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 3 + 38\cdot 47 + 23\cdot 47^{2} + 6\cdot 47^{3} + 16\cdot 47^{4} +O(47^{5})\) |
$r_{ 2 }$ | $=$ | \( 20 + 33\cdot 47 + 22\cdot 47^{2} + 20\cdot 47^{3} + 33\cdot 47^{4} +O(47^{5})\) |
$r_{ 3 }$ | $=$ | \( 34 + 15\cdot 47 + 40\cdot 47^{2} + 28\cdot 47^{3} + 29\cdot 47^{4} +O(47^{5})\) |
$r_{ 4 }$ | $=$ | \( 39 + 6\cdot 47 + 7\cdot 47^{2} + 38\cdot 47^{3} + 14\cdot 47^{4} +O(47^{5})\) |
