The video tutorial covers six types of quadric surfaces: ellipsoids, spheres, one-sheet and two-sheet hyperboloids, cones, and paraboloids. It explains how to identify these surfaces from equations and match them to their graphical representations. The tutorial highlights the importance of the signs and coefficients in the equations, which determine the orientation and shape of the surfaces. Special cases, such as the sphere and single cone, are also discussed.
