subtract the following complex numbers: (4+4i)-(13+17i) ??

Before combining the real parts and the imaginary parts, line them up vertically as follows:
4 + 4i
-13 - 17i
-------------- Now add up each column.
-9 - 13i (Answer A)
Answer:
A ) -9 - 13 i.
Step-by-step explanation:
Given : (4 + 4i) - (13 + 17i) .
To find : subtract the following complex numbers.
Solution : We have given (4 + 4i) - (13 + 17i) .
On removing the parenthesis
4 + 4 i - 13 - 17i.
On combine real part and complex part.
4 - 13 + 4i - 17 i.
-9 - 13 i.
Therefore, A ) -9 - 13 i.
