Can I have a detailed explanation for the part (a) part of the following question?

 

Thank you very much!

(a) Obtain the equation of the tangent plane and the condition for tangency to the conicoid
Ar? + By? + cz? = 1 at the point (a, B, 7).
(b) Find the equation of the tangent plane to the hyperboloid r2 + 3y? – 322 = 1 at the
point (1, -1, 1).
(c) Show that the plane 3r+12y-6z = 17 touches the hyperboloid 3x2 -6y?+922+17 = 0
and find the point of contact.
