Answer:
Option A is correct.
Step-by-step explanation:
We are given:
We need to find the value of a.
The LCM of (2+i) and (3+i) is (2+i)(3+i)
Now rationalize the denominator by multiplying by 5-5i/5-5i
We are given
Now after solving we have:
So value of a = 1/10 and value of b = -1/10
So, Option A is correct.
