Find the equation of the set of points such that the sum of its distances from (0, 3) and (0, -3) is 8.

Explanation

To find the equation of the set of points such that the sum of its distances from the points (0, 3) and (0, -3) is 8, we can follow these steps:

### Step 1: Define the Points and the Required Point
Let the points be:
- A = (0, 3)
- B = (0, -3)

Let P be a point (x, y) in the coordinate plane.
