The binomial formula is (a + b)^2 = a^2 + 2ab + b^2 it is not about (0,

Why not!

 
WEIL ES SO IST.
 
(Ok, you could <bla>

where does that -1 comes from?

 
Das "- 1" in "2*(0 - 1)" war/ist gemeint.
 

It does come from

 
Ja?

As I told in the parallel post:
 ... remember the definition of a complex number: Z = a+bi, i^2 = -1
