Answer to Problem 1E

Solution: The required partial fraction decomposition is:

  53x(2x+1)=53x103(2x+1)

Explanation of Solution

Explanation:Given: The expression 53x(2x+1) .

Formula Used: Set up for partial fraction decomposition for the given expression would be of the form:

  f(x)(xa)(xb)=A(xa)+B(xb)

Calculation: We set up the given expression for partial fraction decomposition as shown below:

  53x(2x+1)=Ax+B2x+1

Now we need to find the values of A and B that satisfy this equation. This can be done as shown below:

  53x( 2x+1)=Ax+B2x+15=3A(2x+1)+3BxUpon comparing coefficients of all the x terms, we get:3A=5A=536A+3B=06(53)+3B=03B=10B=103Thus, the required partial fraction decomposition is:53x( 2x+1)=53x103( 2x+1)

Conclusion: The given expression has been decomposed using partial fractions and the required decomposition has been found to be 53x(2x+1)=53x103(2x+1) .
