Consider the vectors:
Find a subset of the vectors that forms a basis for the space spanned by the vectors.
How do i start?
i have tried to find vectors linearly independant from one other but failed
Carry out a Gaussian row-reduction on the matrix. Ignore any rows that end up as consisting of all zeros. The remaining (nonzero) rows tell you which of the original vectors form a basis for the space that they span. Namely, you take the vectors that were originally in those nonzero rows.
