To add the complex numbers \( (5 + 2i) \) and \( (12 - 5i) \), you combine the real parts and the imaginary parts separately.
1. Add the real parts:
\[
5 + 12 = 17
\]
2. Add the imaginary parts:
\[
2i - 5i = -3i
\]
Now, combine the results:
\[
(5 + 2i) + (12 - 5i) = 17 - 3i
\]
Thus, the result of the addition is \( 17 - 3i \).
The correct response is:
**17−3i**

\]
Thus, the result of the addition is \( 17 - 3i \).
The correct response is:
**17−3i**
