Consider the quadratic matrix equation XTDX +AX +XTB + C = 0, where all the matrices are square and have the same order n. With this equation, a block matrix M of the double order 2n can be associated. The solvability of the equation turns out to be related to the existence of neutral subspaces of dimension n for M. The paper presents reasonably general conditions ensuring the existence of such subspaces.
