Final answer:
The sum of (7-3i)+(-14-6i) is -7-9i.
Step-by-step explanation:
To find the sum of two complex numbers in the form a+bi, you can simply add their real parts separately and their imaginary parts separately. In this case, the real parts are 7 and -14, so their sum is 7+(-14) = -7. The imaginary parts are -3i and -6i, so their sum is -3i+(-6i) = -9i. Therefore, the sum of (7-3i)+(-14-6i) is -7-9i.
