Defining polynomial
$f(x)$ | $=$ | \( x^{5} - x^{4} - 16x^{3} + 36x^{2} + 267x - 319 \) . |
The roots of $f$ are computed in $\Q_{ 67 }$ to precision 6.
Roots:
$r_{ 1 }$ | $=$ | \( 3 + 20\cdot 67 + 55\cdot 67^{2} + 61\cdot 67^{3} + 46\cdot 67^{4} + 56\cdot 67^{5} +O(67^{6})\) |
$r_{ 2 }$ | $=$ | \( 28 + 53\cdot 67 + 47\cdot 67^{2} + 14\cdot 67^{3} + 9\cdot 67^{4} + 67^{5} +O(67^{6})\) |
$r_{ 3 }$ | $=$ | \( 49 + 62\cdot 67 + 53\cdot 67^{2} + 7\cdot 67^{3} + 11\cdot 67^{4} + 55\cdot 67^{5} +O(67^{6})\) |
$r_{ 4 }$ | $=$ | \( 56 + 21\cdot 67 + 25\cdot 67^{2} + 32\cdot 67^{3} + 11\cdot 67^{4} + 22\cdot 67^{5} +O(67^{6})\) |
$r_{ 5 }$ | $=$ | \( 66 + 42\cdot 67 + 18\cdot 67^{2} + 17\cdot 67^{3} + 55\cdot 67^{4} + 65\cdot 67^{5} +O(67^{6})\) |
