Fuller, Basic Matrix Theory, 2017, Dover, page 217, There is an important relationship between the characteristic roots of a symmetric matrix and the r and p of the associated quadratic form. It is true that the number of positive characteristic roots is p, whereas the number of nonzero characteristic roots is r.”

“The determinant of a matrix is the product of its characteristic roots.”
