Find a normal vector to the plane `2x-y+2z=5.` Also, find a unit vector normal to the plane.

Explanation

To find a normal vector to the plane given by the equation \(2x - y + 2z = 5\), we can follow these steps:

### Step 1: Identify the coefficients from the plane equation
The general form of a plane equation is given by:
\[ Ax + By + Cz = D \]
where \(A\), \(B\), and \(C\) are the coefficients of \(x\), \(y\), and \(z\) respectively.

From the equation \(2x - y + 2z = 5\), we can identify:
