Factor the polynomial Z^2 + Zi + 6

 

I don't know where to start, have tried applying the quadratic formula but I can't wrap my head around it.

Some hints please?

Factor of a polynomial with complex number

Factor the polynomial z^2 + zi + 6

 

z^2 + zi + 6 = (z - 2 i) (z + 3 i)

It's that simple? I will work with the answer you gave and see if I can produce the same result.

Thank you so much!
