They are not equal.
Try it with a=1,b=2,c=3.

Why is the value of the determinant of adjoint of a matrix not equal to 1 ?
What is the value of determinant of adjoint( A). What I am not getting in this is that since $AA\ ^{1}=\mathbb{I}_{n}$ .Now if I take determinant on both sides I will get $\mid A\mid \mid A^{1}\mid=\mathbb{I}_{n}=1$ ... $\text{ det(adj(A))}=det(A)^{n1}$

Factor of determinant with identical row
How the following fact applies to determinants (I came across it while solving problems): Consider A is a n× n matrix, the elements of which are real (or complex) polynomials in x. If r rows of the determinant become identical when x ... is collapsing of rows of matrix (into one row) with order of its factors. Am I missing some stupid fact here?
