To calculate:
Write the partial fraction decomposition of the improper rational expression.

Answer to Problem 47E
The partial fraction decomposition of the improper rational expression is
Explanation of Solution
Given information:
Calculation:
Since the degree of the numerator is not less than degree of the denominator, perform polynomial long division.
Now deal with
The form of the partial fraction decomposition is
Write the right hand side as a single fraction.
The denominators are equal, so equate the numerators.
The coefficients are to be equated,
By solving them we get
Therefore,
Conclusion:
The partial fraction decomposition of the improper rational expression is
