WebIf k is not 0 then this is immediate since AA'x is not zero, but for k = 0 you can't rule it out. Indeed for non-square matrices A, it's possible that A' (and hence AA') has a zero eigenvector while A'A is nonsingular, e.g. with A' = [1 0], A'A = [1]. For square A you can argue that if A' has a zero eigenvector then so does A via determinants.
