I have done the following problem over and over and keep getting the same result. So either the book answer is wrong or I am making the same mistake over again:
[tex]\left[\begin{array} {cccc}
5&-2&6&0\\
-2&1&3&1\\
\end{array}\right] [/tex]
[tex]\left[\begin{array} {cccc}
1&-\frac25&\frac65&0\\
-2&1&3&1\\
\end{array}\right] [/tex]
[tex]\left[\begin{array} {cccc}
1&-\frac25&\frac65&0\\
0&\frac15&\frac{17}{5}&1\\
\end{array}\right] [/tex]
[tex]\left[\begin{array} {cccc}
1&0&8&2\\
0&1&17&5\\
\end{array}\right] [/tex]
Am I screwing this up somewhere?
