Answer:
[tex]-2-i[/tex] I'm assuming there's a d option maybe? because this should be the answer
Step-by-step explanation:
Well you have the equation:
r-s
So all you need to do is plug in 1+2i as r, and 3+3i as s, and then you add like terms (kind of like how you can do 2 * sqrt(2) - 3 * sqrt(2) and you simply subtract the "coefficients")
[tex](1+2i)-(3+3i)[/tex]
Distribute the negative sign:
[tex]1+2i-3-3i[/tex]
Combine like terms
[tex](1-3)+(2i-3i)[/tex]
Simplify:
[tex]-2-i[/tex]
