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?
