Defining polynomial
$f(x)$ | $=$ | \( x^{4} - x^{3} + 4x - 1 \) . |
The roots of $f$ are computed in $\Q_{ 223 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 38 + 69\cdot 223 + 123\cdot 223^{2} + 59\cdot 223^{3} + 61\cdot 223^{4} +O(223^{5})\) |
$r_{ 2 }$ | $=$ | \( 83 + 56\cdot 223 + 15\cdot 223^{2} + 123\cdot 223^{3} + 208\cdot 223^{4} +O(223^{5})\) |
$r_{ 3 }$ | $=$ | \( 123 + 222\cdot 223 + 177\cdot 223^{2} + 193\cdot 223^{3} + 130\cdot 223^{4} +O(223^{5})\) |
$r_{ 4 }$ | $=$ | \( 203 + 97\cdot 223 + 129\cdot 223^{2} + 69\cdot 223^{3} + 45\cdot 223^{4} +O(223^{5})\) |
