hmm
aren't there only complex factors (given that none of the coefficients are complex)
and aren't there only 4 factors - from the conjugate theorem?

As far as I think, there are no real roots of your function. But there are 4 complex roots.
I was just wondering what do you want to know?
1. Do you want an algorithm to tell U how many real and complex roots are there?
2. Do you want to find real roots?
3. Do you want to find both the real and complex roots?
What portion you want computer to do?

well seeing this is a maths forum i don't want the computer to do anything.
i don't see how this is hard!
Clearly I already know there are 4 factors and they are complex
I'm asking how to do it! (and what the solution is )
Thanks

(x - cis (2pi / 5)) (x - cis (4pi / 5)) (x - cis (6pi / 5)) (x - cis (8pi / 5))
?

What's cis??
Sql_lall, I enjoyed your solution to this problem. But what is CIS???? I've never seen that nomenclature before...

cis theta = cos theta + i sin theta
i.e. real part = Cos theta
imaginary part = Sin theta

cis.. lol.. e^itheta for me, otherwise it gets confusing
Use
writing software in C++ is like driving rivets into steel beam with a toothpick.
writing haskell makes your life easier:
reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13
To throw away OOP for low level languages is myopia, to keep OOP is hyperopia. To throw away OOP for a high level language is insight.

Yeah. I totally agree with kedaman. Now I get what you were talking about. In Sweden we always write
e^(i*theta)
