Answer 3

It seems like you want to expand the expression (2x + 3)^2. To do this, you can use the distributive property and the formula for squaring a binomial:

(a + b)^2 = a^2 + 2ab + b^2

In your case, a = 2x and b = 3. So, let's apply the formula:

(2x + 3)^2 = (2x)^2 + 2(2x)(3) + (3)^2

Now, simplify each term:

(2x)^2 = 4x^2 2(2x)(3) = 12x (3)^2 = 9

Now, put them all together:

(2x + 3)^2 = 4x^2 + 12x + 9

So, the expanded form of (2x + 3)^2 is 4x^2 + 12x + 9.
