Defining polynomial
$f(x)$ | $=$ | \( x^{4} - 2x^{3} - 2x + 2 \) . |
The roots of $f$ are computed in $\Q_{ 139 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 8 + 50\cdot 139 + 34\cdot 139^{2} + 36\cdot 139^{3} + 27\cdot 139^{4} +O(139^{5})\) |
$r_{ 2 }$ | $=$ | \( 57 + 23\cdot 139 + 49\cdot 139^{2} + 121\cdot 139^{3} + 22\cdot 139^{4} +O(139^{5})\) |
$r_{ 3 }$ | $=$ | \( 91 + 131\cdot 139 + 66\cdot 139^{2} + 30\cdot 139^{3} + 34\cdot 139^{4} +O(139^{5})\) |
$r_{ 4 }$ | $=$ | \( 124 + 72\cdot 139 + 127\cdot 139^{2} + 89\cdot 139^{3} + 54\cdot 139^{4} +O(139^{5})\) |
