(4+3i)^2
(4+3i)(4+3i)
16 + 12i + 12i + 9i^2, where i^2=-1
16 + 24i +9*-1
16 + 24i -9
7+24i

I wrote a whole NON-TRADITIONAL explanation of ALGEBRA, which includes Complex Numbers. The easiest way to find my explanation is to go to my FREE website using the easy-to-remember and easy-to-spell link www.mathinlivingcolor.com. At the bottom of this page is a link that will take you to my Homepage. Look near the top of this page for the link "Basic, Intermediate, and College Algebra: One Step at a Time", click on "Intermediate Algebra." Look in Chapter 3 for "Section 3.06 Complex Numbers." The lesson is complete with explanations, examples, and exercises with all the answers. You will especially like the "MATH IN LIVING COLOR" sections that go with this. I think you will find that my explanations are a LOT easier to understand than the traditional textbooks you are probably using.

Happy New Year!! My Email address is rapaljer@seminolestate.edu if you need to contact me!!
