Answer 1

вот и весь ответ если что оброщайтесь

Answer 2

It seems like you're asking about the product of two expressions: (а-4) and (а+4). The expression you've given is (а-4) * (а+4).

Let's multiply these two expressions using the distributive property (also known as FOIL method):

(а-4) * (а+4) = а * (а+4) - 4 * (а+4)

Now distribute the terms:

= а^2 + 4а - 4а - 16

Notice that the middle terms, 4а and -4а, cancel each other out:

= а^2 - 16

So, the result of the expression (а-4) * (а+4) is а^2 - 16.
