Find the factor of this perfect square trinomials

To factor the given perfect square trinomial \(4g^2 - 4g + 1\), we need to identify it as a square of a binomial.

1. Write down the trinomial:
   \[
   4g^2 - 4g + 1
   \]

2. Recognize the structure of a perfect square trinomial \(a^2 - 2ab + b^2\), which factors to \((a - b)^2\).

3. Identify \(a^2\) and \(b^2\):
   \[
   a^2 = 4g^2 \quad \Rightarrow \quad a = 2g
   \]
   \[
   b^2 = 1 \quad \Rightarrow \quad b = 1
   \]

4. Confirm that the middle term fits the form \(-2ab\):
   \[
   -2ab = -2 \cdot 2g \cdot 1 = -4g
   \]

Since the middle term \(-4g\) matches, we can conclude that the trinomial is indeed a perfect square trinomial. Therefore, it factors to:
\[
(2g - 1)^2
\]

So, the factored form of \(4g^2 - 4g + 1\) is:
\[
(2g - 1)^2
\]
