Hi, the problem I have is the following:
z^2 + 4z + 10, finding the factors over C.
I have gotten up to: (-2 + (sqrt6)i) and (-2 - (sqrt6)i).
I also know, however, that the answers should be
(z + 2 + (sqrt6)i)(z + 2 - (sqrt6)i).
The problem is i can't see how i can change my original answer to this one. What do I need to do?
