Answer:
[tex]5+4i[/tex]
Step-by-step explanation:
[tex](8-5i)-(3-9i)[/tex]
In order to subtract we reverse the sign of the each parameter in the parenthesis followed by the negative sign and change the negative sign in front with positive sign.
[tex](8-5i)+(-3+9i)[/tex]
Simplifying it by removing the parenthesis
[tex]8-5i-3+9i\\[/tex]
Combining like terms.
[tex]8-3-5i+9i[/tex]
[tex]5+4i[/tex]
