the foot of the perpendicular drawn from origin to the plane is the point with coordinates (2,5,7). find the equation of the plane

Let the position vector of  point with coordinates A(2,5,7) be

Direction ratio of OA are 2,5,7.Since OA is perpendicular to plane, a vector normal to plane is ,

Equation of plane through  A and perpendicular to ,is
