equals to

Given,

Now,

Equating ‘ coeff:- Equating ‘

1=A-B 0=A+B

A-B=1

A+B=0

2A=1

A=

B=-

[0-0]

Option A: - it’s not option A , this is clearly justified on solving.

Option B: - it’s not option B , this is clearly justified on solving.

Option C: - it’s not option C, this is clearly justified on solving.
