If z 1 i and z denotes the complex conjugate of z which of

If z = -1 + i and z denotes the complex conjugate of z, which of the following points in the complex plane above represents z + z? Show all your work, step by step

(A) A

(B) B

(C) C

(D) D

(E) E

Solution

z\' = -1+i
z = -1 - i
z+z\' = -1+i -1 - i = -2

Answer: B
