Find the equation to the locus of a point equidistant from the points `A(1,3)a n dB(-2,1)dot`

Explanation

To find the equation of the locus of a point that is equidistant from the points A(1, 3) and B(-2, 1), we can follow these steps:

### Step 1: Define the Point
Let the point P be represented by the coordinates (h, k).

### Step 2: Write the Distance Formulas
The distance from point A to point P (AP) and from point B to point P (BP) can be expressed using the distance formula:
- Distance AP = √[(h - 1)² + (k - 3)²]
