To perform the operation (-6 + 7i) - (3 - 4i) in the form a + bi, subtract the real parts and the imaginary parts separately. The answer is -9 + 11i.
Step-by-step explanation:
To perform the operation (-6 + 7i) - (3 - 4i) in the form a + bi, we need to subtract the real parts and the imaginary parts separately. The real part is -6 - 3 = -9, and the imaginary part is 7i - (-4i) = 7i + 4i = 11i. Therefore, the answer is -9 + 11i.
