- Ans.
det(A- lamda*I) = 0 represents the characteristic equation of a matrix A.

It is used to solve for the values of lambda that satisfy the equation.
The equation is used to determine the behavior of the matrix under certain transformations.
Example: For a 2x2 matrix A, det(A- lamda*I) = 0 gives a quadratic equation to solve for eigenvalues.
