Step-by-step explanation:

Apply the Identity a2 - b2 = (a + b) ( a - b)

Now find the number in which if you add and subtract 2, the numbers of the question will match.

The no. is 95

95 + 2 = 97

95 - 2 = 93

So it is

( 95 + 2)(95 - 2)

(95)² - (2)²

9025 - 4

9021 is the answer of the Evaluation.
