Compute
. Input :
normal(1/rootof([1,0],[1,0,10,0,1]))
P(x) = x is represented by [1,0] and
by rootof([1,0],[1,0,10,0,1]).
Output :
rootof([[-1,0,-10,0],[1,0,10,0,1]])
i.e. :
Compute
2. Input :
normal(rootof([1,0],[1,0,10,0,1])^
2)
or (since P(x) = x2 is represented by [1,0,0]) input
normal(rootof([1,0,0],[1,0,10,0,1]))
Output :
-5-2*sqrt(6)
