The problem is asking to "Find the product" of the two given rational expressions:

\[
\frac{y^2 - 4}{6y - 12} \cdot \frac{y + 6}{y + 2}
\]

Let's break it down step by step:

### Step 1: Factor each expression
- The first numerator \(y^2 - 4\) is a difference of squares and can be factored as:
  \[
  y^2 - 4 = (y - 2)(y + 2)
  \]

- The first denominator \(6y - 12\) has a common factor of 6:
  \[
  6y - 12 = 6(y - 2)
  \]

Now the first fraction becomes:
\[
\frac{(y - 2)(y + 2)}{6(y - 2)}
\]

- The second fraction \(\frac{y + 6}{y + 2}\) cannot be simplified further.

### Step 2: Simplify the product
Now multiply the two simplified expressions:

\[
\frac{(y - 2)(y + 2)}{6(y - 2)} \cdot \frac{y + 6}{y + 2}
\]

Before multiplying, notice that we can cancel the common factors:
- \(y - 2\) appears in both the numerator and denominator, so we can cancel it.
- \(y + 2\) appears in both the numerator and denominator, so we can cancel it as well.

After canceling, we are left with:

\[
\frac{1}{6} \cdot (y + 6)
\]

### Step 3: Multiply the remaining terms
The final product is:

\[
\frac{y + 6}{6}
\]

Thus, the simplified product is:

\[
\frac{y + 6}{6}
\]
