SOLUTION: The expression (-1+i)^3 is equivalent to A) 2+2i B) -1-i C) -3i D) -2-2i I tired doing it but I didn't come up with any of the answers above. I think I did i

Question 372933: The expression (-1+i)^3 is equivalent to
A) 2+2i
B) -1-i
C) -3i
D) -2-2i
I tired doing it but I didn't come up with any of the answers above. I think I did it wrong. So first I do (-1+i)(-1+i)=1-1i-1i+i^2. Then I multiplied
1-1i-1i+i^2 with -1+i. Please help and explain it step by step. Thank you!
