Homework Statement
Find the basis for the row space
The Attempt at a Solution
the given matrix is
0 1 2 1
2 1 0 2
0 2 1 1
So i reduced to row-echeleon form
2 1 0 2
0 1 2 1
0 0 3 1
so then rank = 3. My textbook states that the basis of the row space are the row vectors of leading ones, hence the basis for row space is
{ [2,1,0,2], [0,1,2,1], [0,0,3,1] }
however my textbook has this answer
{ [6,0,0,5], [0,3,0,1]. [0,0,3,1] }
HOW?!??!??! :-(
edit: NVM figured it out. Didnt realize the textbook reduced the matrix to reduced row form.
