If `A` and `B` are square matrices of the same order, then `(A+B)(A-B)` is equal to `A^2-B^2` (b) `A^2-B A-A B-B^2` (c) `A^2-B^2+B A-A B` (d) `A^2-B A+B^2+A B`

Explanation

To solve the problem, we need to simplify the expression \((A + B)(A - B)\) and determine which of the given options it is equal to.

### Step-by-Step Solution:

1. **Start with the Expression**:
\[ (A + B)(A - B) \]
