Wolfram|Alpha gives the 5 roots, two pairs appear to be complex conjugates:
-.808731
-.464912 +/- 1.07147i
.869278 +/- .388269i
(It can't seem to figure out the exact forms)
This means the product sought will be a real number.
Plugging the values into Q, my calculator shows the values 4.999973
which I would guess should actually be 5.
I don't know how to solve exactly.
Note: the product of the 5 roots is -.999995 (probably -1)
