LetA = -2 -1 -3 6 1
1 1 1 -2 1
2 3 1 -2 4
Find a basis for the column space Col(A) of A, and a basis for the null space
Nul(A) of A.
Show that for any matrix A, if u and v are in the null space of A, then
so is u + v.
I know that I have to get the matrix into echelon form inorder to find the pivot points, but when I tried doing this I kept getting different answers when I did it two different ways. It would be really helpful if someone could show me the steps do doing this
