Step-by-step explanation:
Given
Required
Express as partial fraction
Expand the numerator
Factorize
Factor out x + 3
As a partial fraction, we have:
Take LCM
Cancel out (x + 3)^2 on both sides
Open bracket
By comparison, we have:
===> 
Substitute 3 for A
Solve for B
Substitute: and in
Hence, the partial fraction is:
