SUMMARY
The equation of a plane equidistant from two points A(1, 1, 0) and B(5, 3, -2) can be derived by using the normal vector formed by the vector AB. The normal vector is determined by constructing the vector from A to B, which is <4, 2, -2>. The midpoint of A and B, located at (3, 2, -1), serves as a point on the plane. The equation of the plane can be expressed in the form 4(x - 3) + 2(y - 2) - 2(z + 1) = 0, simplifying to 4x + 2y - 2z - 10 = 0.
