If (2i/2+/3+i)=a+bi, then a=
a. 1/10
b. -10
c. 1/50
d. -1/10

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.

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms
