Homework Statement
What is the null space of this matrices.
|1 1 0 3 1|
|0 1 -1 0 1|
|1 1 3 0 1|
The Attempt at a Solution
I reduced it to rref using agumented matrice(each one equals to zero )
|1 0 0 4 0 0|
|0 1 0 -1 1 0|
|0 0 1 -1 0 0|
and i get get x1=-x4 , x2= x4 + -x5, x3 = x4
but then what is the null space??
