What is (-1 i)(-1-i) simplified?

Answer 1

0

Answer 2

You can treat this as a polynomial. Multiply each term on the left with each term on the right, add everything up. Remember that i squared = -1, and remember to group the real and the imaginary parts.

Answer 3

Answer 4

(-1 i)^2 is it simplified.
