The given expression \(16a^2 - 24a + 9\) is a quadratic expression. To factor it, we can recognize it as a perfect square trinomial. A perfect square trinomial takes the form \((ax + b)^2 = a^2x^2 + 2abx + b^2\). We need to identify \(a\) and \(b\) such that the expression matches this form.
Step 1: Identify the Expression
We start with the quadratic expression given by
\[
16a^2 - 24a + 9.
\]
Step 2: Recognize the Perfect Square Trinomial
We can observe that this expression can be factored as a perfect square trinomial. A perfect square trinomial has the form
