Answer:
[tex] \boxed{ \bold{ \huge{\boxed{ \sf{ - 3i + 1}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{(4 + 2i) + ( - 3 - 5i)}[/tex]
When there is a ( + ) in front of an expression in parentheses, there is no need to change the sign.
That means the expression remains the same.
Just remove the parentheses
[tex] \sf{4 + 2i - 3 - 5i}[/tex]
Collect like terms
⇒[tex] \sf{ - 3i + 4 - 3}[/tex]
Calculate the difference
⇒[tex] \sf{ - 3i + 1}[/tex]
Hope I helped!
Best regards!!

Answer:
1 -3i
Step-by-step explanation:
For purposes of addition or subtraction, the i can be treated as though it were a variable. Terms can be collected in the usual way.
4 +2i +(-3 -5i) = 4 +2i -3 -5i
= (4 -3) +i(2 -5) = 1 -3i
