I need to find the echelon form of:
1 1 2 8
-1 -2 3 1
3 -7 4 10
and so far I have:
1 1 2 8
0 10 -50 -90
0 0 -52 -104
I was just wondering if I was required to put another zero in my third row. Am I always required to have three zeros in the third row? I'm assuming I do, but when I looked at the solution for this problem I found it to be:
1 1 2 8
0 1 -5 -9
0 0 1 2
However this solution does not have three zeros in the third row, when all of the other problems and solutions did have three zeros.
My apologies for the misaligned matrix, I am still getting used to Physics Forum.
Thank you.
