Question 2 • Fall 24 GMS Advanced Algebra: Concepts and Connections A

What is the value of (–7 + 3i) – (2 – 6i)?

Answer
A
–9 + 9i
B
–9 – 3i
C
–5 – 3i
D
–5 + 9i

Explanation

Subtract the real and imaginary parts separately: (–7 + 3i) – (2 – 6i) = –7 + 3i – 2 + 6i. The real parts give –7 – 2 = –9, and the imaginary parts give 3i + 6i = 9i. The result is –9 + 9i, choice A.
