missed class: reduce matrix to red. echelon form

Postby BuzzieCat » Thu Sep 08, 2011 10:02 am

well im stuck on this matrices, the question says reduce the matrix to its reduced echelon form... unfortunately I missed last lecture and don't know this material.. if anyone can solve and showing each step it would help a ton, thanks.


reduce the matrix to its reduced echelon form:

[ 1 4 -2 |7]
[ 2 5 2 |2 ]
[ 0 3 2 |5 ]

To learn what "echelon form" is, try here. To learn how to do the row operations on the matrix (in order to get that form), try here. :wink:
