Determine the partial fraction decomposition of `(9x+25)/((x+3)^2))`

Explanation

To determine the partial fraction decomposition of the expression \(\frac{9x + 25}{(x + 3)^2}\), we will follow these steps:

### Step 1: Set up the partial fraction decomposition
We express \(\frac{9x + 25}{(x + 3)^2}\) in the form:
\[ \frac{A}{x + 3} + \frac{B}{(x + 3)^2} \]
where \(A\) and \(B\) are constants that we need to determine.
