Proving A Must Be of Rank 2: The 2x2 Matrix Dilemma

[QUOTE="andrewkirk, post: 6541203, member: 265790"] You don't have to show that A has rank 2. You are given that as a premise. I don't know why they give you that as a premise though, because the theorem is true for [B]any [/B]matrix, not just any rank-2 matrix, as your proof shows. Anyway, you have proven what they asked you to. [/QUOTE]
