Homework Help: Algebra II

Posted by Paige on Thursday, October 15, 2009 at 8:51pm.

The answer for (7+5i)+(-4+2i) is 3+7i. But I got -38-6i. I combined -28 and 10i^2 to get -38, and I combined -20i and 14i to get -6il So all together this was -28+-6i+-10, which resulted in -38-6i. Could you please tell me where I went wrong?
