Answer 1

2а во второй степени - 9

Answer 2

(2a+3)(2a-3)=4a^2-9-это формула сокращенного умножения

Answer 3

Converting the Expression into a Polynomial

To convert the expression (2a + 3)(2a - 3) into a polynomial, we can use the distributive property. This property states that for any real numbers a, b, and c, the product of a and the sum of b and c is equal to the sum of the products of a and b and a and c.

Applying the distributive property to the given expression, we have:

(2a + 3)(2a - 3) = 2a * 2a + 2a * (-3) + 3 * 2a + 3 * (-3)

Simplifying this expression, we get:

4a^2 - 6a + 6a - 9

Combining like terms, we have:

4a^2 - 9

Therefore, the polynomial form of the expression (2a + 3)(2a - 3) is 4a^2 - 9.
