Question on linear dependence: Where do I go wrong?
Hello,

I tried to find a solution (see attachment) to the exercise in the attachment, but somehow I end up with two values for k that do not result in linear dependent vectors. Where do I go wrong? What SHOULD I do? And what are the right values for k?

you dropped a minus sign in the third row in the second column.

what you should have ended up with, in the 3,3 position is:

$1 - \frac{4}{k} + \frac{3}{k} - \frac{2}{k^2}$
