If I want to find if(adsbygoogle = window.adsbygoogle || []).push({});

span ([4, 0, -3], [2,2,1]) = span ([2,-2,-4], [0,1,5]) do I first find their reduced row echelon form, and then see if they match? For instance, if I found both matrices to reduce to:

[ 1 0]

[ 0 1]

[ 0 0]

does that mean that they equal each other? Or do I have to do something else?

Also what is the vector space? Is it R2 in this case?
