MHB Power Flow Calculation for Generator Node: Understanding Different Results

[aruwin]

Hello.
This is a power flow calculation of the generator node. I tried calculating several times but I still do not get the same values as this one. This one is the answer, by the way. Can someone explain to me why I got a different answer?

I got:
$$P2=−1.25e_1f_2−1.25e_2f_1+4.32e_2f_1−e_3f_2−e_2f_3$$

It's alright now. I just realized the *symbol means complex conjugate.
