Determine whether the given partial fraction decomposition is set up correctly. If the setup is incorrect, make the necessary changes to produce the correct decomposition.
4x/(x + 1)(x-3)²=A/(x+1)+B/(x-3)+ C/(x-3)
Select the correct choice below and, if necessary, fill in the answer box to complete your choice. Do not solve for the constants.
A. The partial fraction decomposition is incorrect. The correct partial fraction decomposition is 4x/(x + 1)(x-3)²=____
B. The partial fraction decomposition is correct.
