Answer 2

To simplify the expression, let's expand and simplify the given expression step by step:

25(в кв.) - (a + 3)²

First, let's expand the square:

25(в кв.) - (a + 3)(a + 3)

Using the distributive property, we can multiply (a + 3) by itself:

25(в кв.) - (a² + 3a + 3a + 9)

Simplifying further:

25(в кв.) - (a² + 6a + 9)

Next, distribute the 25 across the expression:

25в² - a² - 6a - 9

Finally, rearrange the terms in descending order:

25в² - a² - 6a - 9

So the simplified expression is 25в² - a² - 6a - 9.
