(adsbygoogle = window.adsbygoogle || []).push({}); use rowspace/colspace to determine a basis for the subspace of R^n spanned by the given set of vectors:

{(1,-1,2),(5,-4,1),(7,-5,-4)}

*note: the actual instructions are to use the ideas in the section to determine the basis, but the only two things learned in the section are rowspace and colspace.

3. The attempt at a solution

- I thought you could just find the rowspace, and that would be a subspace of R^n, but the answer in the back of the book isn't at all the same. How would you go about solving this problem?
