On the basis of the eigenvalues of A, classify the quadratic surfaces
X'AX+BX+k=0
into ellipsoids, hyperboloids, paraboloids and cylindres.

Can somebody help me to solve the problem?

Hi FilipVz, welcome to MHB! :)

That is a pretty generic question.
The best I can do is to refer you to the relevant wiki article about Quadrics.
 
The world of 2\times 2 complex matrices is very colorful. They form a Banach-algebra, they act on spinors, they contain the quaternions, SU(2), su(2), SL(2,\mathbb C), sl(2,\mathbb C). Furthermore, with the determinant as Euclidean or pseudo-Euclidean norm, isu(2) is a 3-dimensional Euclidean space, \mathbb RI\oplus isu(2) is a Minkowski space with signature (1,3), i\mathbb RI\oplus su(2) is a Minkowski space with signature (3,1), SU(2) is the double cover of SO(3), sl(2,\mathbb C) is the...
