Defining polynomial
$f(x)$ | $=$ | \( x^{4} - x^{3} + 7x + 14 \) . |
The roots of $f$ are computed in $\Q_{ 71 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 6 + 64\cdot 71 + 25\cdot 71^{2} + 38\cdot 71^{3} + 65\cdot 71^{4} +O(71^{5})\) |
$r_{ 2 }$ | $=$ | \( 14 + 12\cdot 71 + 25\cdot 71^{2} + 49\cdot 71^{3} + 50\cdot 71^{4} +O(71^{5})\) |
$r_{ 3 }$ | $=$ | \( 21 + 20\cdot 71 + 55\cdot 71^{2} + 26\cdot 71^{3} + 38\cdot 71^{4} +O(71^{5})\) |
$r_{ 4 }$ | $=$ | \( 31 + 45\cdot 71 + 35\cdot 71^{2} + 27\cdot 71^{3} + 58\cdot 71^{4} +O(71^{5})\) |
