Which of the following is a partial fraction of
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Given, -x2+6x+13(3x+5)x2+4x+4 =-x2+6x+13(3x+5)x+22 Using Partial fraction rules, we get -x2+6x+13(3x+5)x+22=A3x+5+Bx+2+Cx+22 ⇒-x2+6x+13=Ax+22+Bx+23x+5+C3x+5 Putting x=-2, we get C=3 Putting x=-53, we get A=2 and on comparing coefficients of x2, we get B=-1 i.e.…
