Question

if the eigen values of matrix A of order 3*3 are (2,3,1)then find the eigen values of adjointA

Answer 1

Answer:

If the Eigen values of the matrix A of order 3 X 3 are 2, 3 and 1,

then find the determinant of A

Answer 2

Answer: The eigen values of adjoint A are 3,2 and 6.

Step-by-step explanation:

det A = Product of eigen values of A

det A  = 2 x 3 x 1

det A = 6

Eigen values of adjoint A = $\frac{det A}{Eigen value of A}$

Eigen values of adjoint A = $\frac{6}{2} , \frac{6}{3} , \frac{6}{1}$

Eigen values of adjoint A = 3,2,6
