I can find what z is, but I am not sure how they jumped straight into |z - (1+i)| = 4? I understand how that translates into the information on the argand diagram but I'm missing how they did that first step.

I can find z = +-sqrt(2) (1 + i) aswell which is promising
but then i'm still not 100% confident on getting that (1+i) in there
