Answer to Problem 16.7EAA
The required partial fraction decomposition of the given rational expression is
Therefore, option (b) is the correct answer.
Explanation of Solution
Given information:
A rational expression:
Calculation:
First of all, we factor the quadratic in the denominator:
The given rational expression becomes:
Now we set up the partial fraction composition as shown below:
Upon multiplying by
Now we need to find the values of A, B, C and D by substituting some values of x.
We have the values of B and D. In order to get the values of A and C, we solve the system of linear equations:
Upon substituting
Conclusion:
The required partial fraction decomposition of the given rational expression is
