To perform subtraction of complex numbers, it is necessary to group both real terms and both imaginary terms together before simplifying. This is done as follows:
(–7 + 3i) – (2 – 6i) (–7 + 3i) + (-2 + 6i)
Grouping similar terms: (-7 + -2) + (3i + 6i)
Simplifying: -9 + 9i
From the choices, the correct answer is A.
