WebNow, as isn't invertible, this implies , thus completing the proof. [Case II] det (Adj (A)) = nonzero, so Adj (A) is invertible. Let (Adj (A))^ {-1} =B. From A Adj (A)=det (A)I, A Adj (A) B= det (A)I B. Suppose that det (A)=0. Then A = 0. So Adj A =0 implies det (Adj A)=0, a contradiction. Therefore det (A) = nonzero.
