Find the equation of the plane passing through `A(2,2,-1),B(3,4,` `2)a n dC(7,0,6)dot` Also find a unit vector perpendicular to this plane.

Explanation

To find the equation of the plane passing through the points A(2,2,-1), B(3,4,2), and C(7,0,6), and to find a unit vector perpendicular to this plane, we can follow these steps:

### Step 1: Identify the Points
We have three points:
- A(2, 2, -1)
- B(3, 4, 2)
- C(7, 0, 6)
