The equation given in the image is \( x^2 + 4x + 4 = 0 \), and the question asks for one of the factors of this quadratic equation.

We can factor the quadratic expression \( x^2 + 4x + 4 \).

1. First, recognize that this is a perfect square trinomial. The general form of a perfect square trinomial is \( (x + a)^2 = x^2 + 2ax + a^2 \).
2. In this case, \( 4x \) is twice the value of 2, and \( 4 \) is the square of 2. So, we can rewrite the quadratic expression as:
   \[
   x^2 + 4x + 4 = (x + 2)^2
   \]
   
Thus, the factors of the quadratic equation are \( (x + 2)(x + 2) \), and one of the factors is \( (x + 2) \).

The correct answer is **A. (x + 2)**.
