Factorize each of the following expressions by splitting the middle term: `9(x-2y)^2-4(x-2y)-13`

Explanation

To factorize the expression \(9(x-2y)^2 - 4(x-2y) - 13\) by splitting the middle term, we can follow these steps:

### Step 1: Substitute the variable
Let \(p = x - 2y\). Then, we can rewrite the expression as:
\[ 9p^2 - 4p - 13 \]
