Three Dimensional Geometry

If \(\mathrm{A}\) and \(\mathrm{B}\) are the foot of the perpendicular drawn from the point \(\mathrm{Q}(\mathrm{a}, \mathrm{b}, \mathrm{c})\) to the planes \(\mathrm{YZ}\) and \(\mathrm{ZX}\) respectively, then the equation of the plane through the points \(\mathrm{A}, \mathrm{B}\), and \(\mathrm{O}\) is (where \(\mathrm{O}\) is the origin)
