Homework Statement
Find a basis for the kernel space of the following matrix:
-1 -2 -1 2 2
-2 -4 -4 10 2
1 2 2 -5 2
-1 -2 0 -1 0
row reduce to
1 2 0 1 0
0 0 1 -3 0
0 0 0 0 1
0 0 0 0 0
Somehow read the solution as
{ [-2 1 0 0 0]T, [-1 0 3 1 0]T }
.. I don't understand how to read the basis from the RREF. Could someone shed some light for me? Thanks so much!
