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?

Thanks
