Recall that by definition of what it means to be an imaginary number.

So,

We do not involve the plus/minus in this case. This is because the result of the square root function is one output only.
Input = -9 leads to output = 3i

Therefore,

The complex number is of the form a+bi
a = -6 = real part
b = 3 = imaginary part
