Best ResponseYou've already chosen the best response.1i think you mean the latter \[\text{ so we have } \frac{3+2i}{32i}\] do you know to put it in a+bi form the first step you must take is to multiply both top and bottom by bottom's conjugate

Best ResponseYou've already chosen the best response.0@myininaya yes i multiplied the top and bottom by 3+2i and got 9+6i+6i+4i^2 over 9+6i6i4i^2 and got the final answer as 9+12i / 9 but its the wrong answer

Best ResponseYou've already chosen the best response.1so you got it right so far to say \[\frac{9+6i+6i+4i^2}{9+6i6i4i^2}\]

Best ResponseYou've already chosen the best response.1and you know again i^2 is 1 so you have \[\frac{9+12i+4(1)}{94(1)}\] wherever there was an i^2 i just replaced it with 1
