Help With Imaginary Numbers?
Im sorry if this is long, but I need help. Thank you so much in advance! In my Algebra class we're learning about imaginary numbers, I have a test tomorrow, and I'm not sure if I have the hang of it. One of my assigned problems is  Simplify each expression: (2 + 4i) + (4  i) and I got 6 + 3i. is that right? One is: 6  (8 + 3i) and I don't know how to do that. Would it be 2 + 3i? One is (2i)(5i) and I don't know how to multiply them. One is (9+4i)2 ( as in squared). Any help is greatly appreciated.
