Answer:
[tex]5-15i[/tex]
Step-by-step explanation:
Simplify (9 − 5i) − (4 + 10i)
[tex](9 - 5i) - (4 + 10i)[/tex]
To subtract we multiply the negative sign inside the second parenthesis
[tex]9 - 5i - 4 - 10i[/tex]
Now combine like terms
[tex]-5i-10i=-15i[/tex]
[tex]9-4=5[/tex]
[tex](9 - 5i) - (4 + 10i)=-15i+5[/tex]
We write it in a+ib form
[tex]5-15i[/tex]
