A) \[1\]
B) \[2\]
C) \[9/4\]
D) \[-1/4\]
Correct Answer: B
Solution :
\[\therefore \]\[(2x+3)=a(x-3)+b(x+1)\] Put\[x=-1\]and\[x=3\]respectively, we get \[1=-4a\]and \[9=4b\] \[\Rightarrow \,\,\,a=-\frac{1}{4}\] and \[b=\frac{9}{4}\] \[\therefore \] \[a+b=-\frac{1}{4}+\frac{9}{4}=2\]You need to login to perform this action.
