Final Answer: The simplified form of the expression $(3 x-2)(3 x+2)$ is $\boxed{9x^2 - 4}$.

Steps

Step 1 ：Given the expression $(3 x-2)(3 x+2)$, we need to simplify it.

Step 2 ：First, we apply the distributive property, which states that $a(b + c) = ab + ac$ and $a(b - c) = ab - ac$.

Step 3 ：Applying this to our expression, we get $9x^2 - 4$.

Step 4 ：Final Answer: The simplified form of the expression $(3 x-2)(3 x+2)$ is $\boxed{9x^2 - 4}$.
