Im a little confused here and I have a feeling I forgot how to do matrix operations. The problem is to determine whether or not the following equation is dependant or independent.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]u = (1, - 1,2),v = (3,0,1),w = (1, - 2,2)[/tex]

I thought that I setup the matrix like this and try to look for the echelon form:

[tex]\begin{array}{*{20}c}

1 & 3 & 1 \\

{ - 1} & 0 & { - 2} \\

2 & 1 & 2 \\

\end{array}[/tex]

I got it down to:

[tex]\begin{array}{*{20}c}

1 & 0 & 1 \\

0 & { - 5} & 0 \\

0 & 3 & { - 1} \\

\end{array}[/tex]

and I got a little confused, im not sure what to do… or maybe I screwed up earlier?
