Why is the sum of (1+3i) and its conjugate pair equal 2? My teacher did this, but I still don't understand the workout. Can someone please explain?

hartnn (hartnn):

you know what conjugate means ?

OpenStudy (azureilai):

Yes it would be 1-3i

hartnn (hartnn):

good! now take thier sum 1+3i + 1- 3i what gets cancelled ?

OpenStudy (azureilai):

Ok, I see. the 3i's would get cancelled. I was thinking of it being multipiled together.

hartnn (hartnn):

any more doubts ?

OpenStudy (azureilai):

nope, thank you for helping
