Step 1: Identify the expression (a - b)(a + b).
Step 2: Recognize that this expression is a special case called the difference of squares.
Step 3: Recall the formula for the difference of squares, which is (x - y)(x + y) = x² - y².
Step 4: In our case, let x = a and y = b.
Step 5: Apply the formula: (a - b)(a + b) = a² - b².
Step 6: Conclude that the result of (a - b)(a + b) is a² - b².
