Evaluate: `int1/(3-2x-x^2)\ dx`

Explanation

To evaluate the integral \( \int \frac{1}{3 - 2x - x^2} \, dx \), we can follow these steps:

### Step 1: Rewrite the Denominator
First, we rewrite the denominator in a more manageable form. We can rearrange the quadratic expression:

\[ 3 - 2x - x^2 = -(x^2 + 2x - 3) \]
