the real part stays the same and the imaginary part changes sign

i get feelings all the time but in math definitions and logic must corroborate the feelings

anonymous · Answer

you have to change the sign on the imaginary term to get the conjugate.

now she hears me...

anonymous · Answer

not b, c.  -4 is the real part.  the sign on the imaginary part changes sign.

so -4 + 2 i is the original and -4 - 2i is the conjugate.
