Complex conjugates

Question

Find the sum of -1+6i and its complex conjugate write your answer in the form of a+bi

please help

Answer 1

(-1 + 6i) + (-1 - 6i) = -2

The complex conjugate of a + bi is a - bi.

Answer 2

-1 + 6i has a conjugate = 1-6i

sum them cancels out the imaginary part and leaves -1-1=-2

in more express a+bi form you could also write that as

= -2 +(0)i with a=-2, b=0
