I can't seem to figure this one out.

z 2 + 4bz + 16b 2 = (z + ?b)(z + ?b)

I can't seem to figure out what would be the product of 16 and the sum of 4. I believe both of these are to be positive so I'm at a lost.

the terms that replace the question marks ("?") in your factorization:

2*(1+i*sqrt(3)) and 2*(1-i*sqrt(3))
