[Faze]

use the fact that i^2 = -1 and a/b + c/d = (ad + bc)/bd

((2+i)/(1-i))+((1)/(1+2i)) - Wolfram|Alpha

EDIT: Well, for some reason it doesn't show you how to work it out. Usually it does. Maybe it's a one step thing?

 

[Baby Bew]

This problem is too complex for me.

 

[Azn_Essence]

it comes to 4i+1 over 3+i

WTF WHAT IS NETZ HOW I GET 7/10

 

[skysnipe]

Only faggots take calculus.

 

[hyung]

dude u r pretty dumb

 

[Shiloh]

multiply the left part by (1 + i)/(1 + i) and the right part by (1 - 2i)/(1 - 2i).

You should be able to handle the rest.
