Hi! First off, great forum, used it as a guide for quite some time :)

So, got a problem, polynomials isnt my strongest suit i guess, so here goes:

Find all the complex solutions to the equation:

z^4 − z^2 + 3 = 0

Then factorize z^4 − z^2 + 3, first in complex first grade polynomials, then in second grade?
