Find `intsqrt(3-2x-x^2)dx`

Explanation

To solve the integral \(\int \sqrt{3 - 2x - x^2} \, dx\), we will follow a series of steps to simplify and evaluate the integral.

### Step 1: Rewrite the expression under the square root
We start with the expression \(3 - 2x - x^2\). To make it easier to integrate, we can rearrange it:

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