To find: The Partial fraction decomposition of the rational function
Answer to Problem 88RE
The partial decomposition is
Explanation of Solution
Given:
Calculation:
Consider the rational function
To find the partial function decomposition write the denominator as the product of factors
Compare the coefficients of
Finally the last term is
This gives the system
Multiply (1) with 2 and add to the (2)
Call this asequation (4)
Multiply (4) equation with 2 and add to theequation (3)
Use the value of Ain theequation (1),
So
Also use
Replace A,B,C values in (1), the required partial decomposition is
Conclusion:
Hence,the partial decomposition of the rational function
