To find:The partial fraction decomposition of the given improper rational expression.
Answer to Problem 48E
The partial fraction decomposition of the given improper rational expression is
Explanation of Solution
Given information:
The improper rational expression is
Calculations:
Since the given rational expression is improper, lets expand the denominator and begin by dividing the numerator by the denominator.
Expansion of
Therefore, the long division result is
Now, continuing the partial fraction on remainder, the decomposition form is as follows:
Now, multiply each side by the least common multiple,
That is,
Comparing the coefficients of like terms, we get
Using
Then,
And
Conclusion:
Therefore, the partial fraction decomposition of the given improper rational expression is
