The difference of squares formula is $a^2 - b^2 = (a - b)(a + b)$ .

Identify 'a' and 'b' in the expression $73.8^2 - 26.2^2$ .
Here, $a = 73.8$ and $b = 26.2$ .
Apply the difference of squares formula.
$73.8^2 - 26.2^2 = (73.8 - 26.2)(73.8 + 26.2)$
Calculate the values inside the parentheses.
$73.8 - 26.2 = 47.6$
$73.8 + 26.2 = 100$
Multiply the results from Step 3.
$47.6 \times 100 = 4760$
$73.8^2 - 26.2^2 = 4760$
The answer is 4760.
