If A and B are symmetric matrices, then
(i) AB-BA is a ..........
(ii) BA-2AB is a.............

Explanation

To solve the problem, we need to analyze the expressions \( AB - BA \) and \( BA - 2AB \) given that \( A \) and \( B \) are symmetric matrices.

### Step-by-Step Solution:

1. **Understanding Symmetric Matrices**:
- A matrix \( A \) is symmetric if \( A^T = A \).
- Similarly, for matrix \( B \), we have \( B^T = B \).
