Question 13 • Fall 24 GMS Advanced Algebra: Concepts and Connections A
Correct Answer:
No, the work is incorrect. When subtracting $(3 10i)$, the subtraction sign must be distributed to both terms in the parentheses. This means $(10i)$ should become $10i$. The correct steps should be: $11 2i 3 10i (11 3) (2i 10i) 8 12i$.
