Perform the indicated operations and write the answer in the form a + bi, where a and b are real numbers.
Problem #1 (3+2i)squared
Problem #2 icubed-isquared
#1 Multip[ly out (3 + 2i)^2 and use the fact that i^2 = -1.
#2 i^2 = -1, and i^3 = -i
Add the two terms for the answer
I need this in a final answer form please :)
Then go somewhere else. We are here to help you learn, not do your work for you.
Wow drwls....that was pretty rude and entirely unnecessary!!
Actually Dawn, I agree with him. You are looking for answers, not help. See my post on the other.

Show us your steps in the future and we'll gladly tell you where you went wrong, if the problem happens again.
I did in the math post I did right after this one....perhaps u can see if I still did it wrong? Thanks.....
