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

Explanation

To find the integral of the expression \( \sqrt{3 - 2x - x^2} \, dx \), we will follow these steps:

### Step 1: Rewrite the expression under the square root
First, we need to rewrite the quadratic expression \( 3 - 2x - x^2 \) in a more manageable form. We can rearrange it as follows:

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