Hi,
I am having trouble with this question:
With these two matrices,
$\displaystyle \left(\begin{array}{ccc}2&0&1\\1&3&1\\5&-3&2\end{array}\right)$ and $\displaystyle \left(\begin{array}{ccc}1&a&b\\a&1&c\\b&c&a\end{ar ray}\right)$
What numbers a, b, and c make them row-equivalent
I know that if their row equivalent, they have to have the same reduced row echelon form. So I tried approaching it from this angle, but I can't really transform the second matrix to a reduced-row echelon form
Any suggestions?
