Answer:
-1/6 - 1/6 i.
Explanation:
We multiply top and bottom of the fraction by the complement of - 3 - 15i which is - 3 + 15i.
-2 + 3i (-2 + 3i)(-3 + 15i) 6 -9i - 30i - 45 -39 - 39i
--------- = ---------------------- = ---------------------- = --------------
-3 - 15i (-3 - 15i) (-3 + 15i) 9 -225 * -1 234
= 39 ( -1 - i) / 234
= -1/6 - 1/6 i
