Use either a suitable identity or the distributive property to find each of the following products.

\((5a – 10b) (5a + 10b)\)

The expansion of the given product is found using the identity of:

\((a+b)^2\)
\(a^2-b^2\)
None of these
\((a-b)^2\)

\((5a – 10b) (5a + 10b)\) \(=\)

$25 a^{2} + 100 b^{2}$
$100 a^{2} - 25 b^{2}$
$25 b^{2} - 100 a^{2}$
$25 a^{2} - 100 b^{2}$
