Question

I can’t seem to find the soultion

Answer 1

Answer:

$-2-i$ 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")

$(1+2i)-(3+3i)$

Distribute the negative sign:

$1+2i-3-3i$

Combine like terms

$(1-3)+(2i-3i)$

Simplify:

$-2-i$
