... The values of are the eigenvalues of the system. If the quadratic formula discriminant, √ , is positive, the matrix will have two distinct, real roots. If the discriminant is 0, the system has 1 real root. If the discriminant is negative, the system will have two complex roots. The eigenvalues are t ...
