Question

Subtract the following complex numbers:
(11 - 9i) - (15 - 12i)

Answer 1

-4 + 3i

To subtract the complex numbers (11 - 9i) and (15 - 12i), subtract the real parts and imaginary parts separately to get the final answer, which is -4 + 3i.

Step-by-step explanation:

The question involves subtracting complex numbers. To subtract the complex numbers (11 - 9i) and (15 - 12i), you simply subtract the real parts and the imaginary parts separately. Here's the step-by-step process:

1. Subtract the real parts: 11 - 15 = -4.
2. Subtract the imaginary parts: (-9i) - (-12i) = -9i + 12i = 3i.
3. Combine the results from steps 1 and 2 to get the final answer: -4 + 3i.

Therefore, the result of subtracting the complex numbers (11 - 9i) from (15 - 12i) is -4 + 3i.
