Question

The sum of two complex numbers, where the real numbers do not equal zero, results in a sum of 34i. Which statement must be true about the complex numbers?
A.The complex numbers have equal imaginary coefficients.
B.The complex numbers have equal real numbers.
C.The complex numbers have opposite imaginary coefficients.
D.The complex numbers have opposite real numbers.

Answer 1

Let's make an example of 2 complex numbers that sum to 34i
How about:
5 + 30i and -5 + 4i
Add those together and you get
(5 + (-5)) + (30 + 4)i =
0 + 34i
34i
Why did they sum to 34 i with no real part in the answer?

Answer 2
