Find the product: `(2x-y+3z)(4x^2+y^2+9z^2+2x y+3y z-6x z)`

Explanation

To find the product of the expression \((2x - y + 3z)(4x^2 + y^2 + 9z^2 + 2xy + 3yz - 6xz)\), we can use the identity for the product of a trinomial and a specific polynomial form.

### Step-by-Step Solution:

1. **Identify the terms**: We have the first polynomial \(A = 2x - y + 3z\) and the second polynomial \(B = 4x^2 + y^2 + 9z^2 + 2xy + 3yz - 6xz\).

2. **Rewrite the second polynomial**: Notice that the second polynomial can be rearranged as:
\[
