Hello,

I am not sure what to do with the zero vector in this question..thanks.

ﬁnd a basis for Span(X), and say whether or not Span(X) is equal to the vector space R^n of which X is a subset.

x={(1 2 3),(4 5 6),(0 0 0) which is a subset of R^3

what does one do with the (0 0 0) vector ? is it a multiple of something ?

please note ..each bracketed item represents a column vector not a row vector..
