If we have that B is a symmetric matrix (B is equal to its transposed matrix) and, in addition, it is satisfied that (X' + 22B) BX = 3B, then the matrix X is given by: a) -19(B - I "B. , provided that B Iis a non singular matrix (is invertible) b) -19(T B)'B. Provided that I- B is a non singular matrix (is invertible) c) - 19B(T B) provided that I-B is a non-singular matrix (is invertible) provided that B-I is a non-singular matrix (is invertible) d) -19B(B -I)',
