WebHere's an alternative method: take any old basis of R 3 (hint: there's an obvious choice here that's very convenient), and show that any vector expressed in that basis can be expressed as a linear combination of your set of vectors. ogdredweary • 10 yr. ago all linear algebra problems are row-reduction problems. put the vectors in a matrix. -2 WebA quick solution is to note that any basis of R 3 must consist of three vectors. Thus S cannot be a basis as S contains only two vectors. Another solution is to describe the span Span ( S). Note that a vector v = [ a b c] is in Span ( S) if and only if …
