Determine whether or not the given matrix A is diagonalizable. If it is, find a diagonalizing matrix P and diagonal matrix D such that P 1 AP = D. 3 -2 2 - - 1 Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The matrix is diagonalizable, {P,D} = { }. (Use a comma to separate matrices as needed.) B. The matrix is not diagonalizable.
