Defining polynomial
$f(x)$ | $=$ | \( x^{5} - 2x^{4} - 4x^{3} + 5x^{2} + 3x - 1 \) . |
The roots of $f$ are computed in an extension of $\Q_{ 19 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 19 }$: \( x^{2} + 18x + 2 \)
Roots:
$r_{ 1 }$ | $=$ | \( 7 a + 9 + \left(6 a + 14\right)\cdot 19 + \left(2 a + 14\right)\cdot 19^{2} + \left(14 a + 7\right)\cdot 19^{3} + \left(2 a + 8\right)\cdot 19^{4} +O(19^{5})\) |
$r_{ 2 }$ | $=$ | \( 5 a + 6 + \left(4 a + 8\right)\cdot 19 + 2\cdot 19^{2} + \left(12 a + 8\right)\cdot 19^{3} + 2\cdot 19^{4} +O(19^{5})\) |
