Find a linearly independent set of vectors that spans the same subspace of R^3 as that spanned by the vectors
[tex] \left(\begin{array}{c} -2 & -1 & -2 \end{array}\right) ,
\left(\begin{array}{c} -2 & 3 & -8 \end{array}\right) ,
\left(\begin{array}{c} 0 & -2 & 3 \end{array}\right)
[/tex]
I'm not sure how to find a linearly independent vector. For a linearly dependency, the determinant of the matrix cannot equal zero. But how would i find two other 3x1 vectors that does not have linear dependency?
