Hi. I'm having some trouble factoring complex polynomials. I'm sure it's very easy assignments, but I'm missing some key-information as to how to solve these tasks.(adsbygoogle = window.adsbygoogle || []).push({});

Tasks:

The task is to find the complex and real factors of the polynomials(since I'm not that articulate in english I will provide the answer for the first task, just so it's easier to see what type of answers the task is looking for)

a) z^{3}+ 8

b) z^{4}- 1

c) I will provide this one if I still don't get it.

(I decided to list two tasks since I find that it is easier to compare the solution to different tasks than to just try and understand how one solution works. However, at this point I'm happy with any help I can get, since I'm pretty much stuck).

Answer:

a) (z + 2)(z - 1 - i[itex]\sqrt{3}[/itex])(z - 1 + i[itex]\sqrt{3}[/itex]) = (z + 2)(z^{2}- 2z + 4)

(Side note: i = [itex]\sqrt{-1}[/itex])

PS: telling me how to aproach the task and solve it is just as good(if not better), than just solving the task. Then I can actually try to solve it myself.

Thanks, Noorac=)
