Explanation:

Let's solve 107 x 93:

- 107 x 93 = (100 + 7) x (100 - 7)

- This matches the formula (a + b) x (a - b) = a² - b²

- Here, a = 100 and b = 7.

- So, 100² - 7² = 10000 - 49 = 9951

Now, let's look at the options:

- Option 1: 10047

- Option 2: 9951

- Option 3: 10049

- Option 4: 9953

Option 2 is the correct answer.
