a) Find all solutions of the equation. (Write your answers in the form a + bi. Enter your answers as a comma-separated list.)
Answers I got for this is -2 + 2i and -2-2i..I assume you just use the quadratic formula and solve..is that right?
b) Find the indicated power using De Moivre's Theorem.
Don't know if I did it right, but I got 1024i for this problem..can someone verify?
