[SOLVED] basis of a null space
Find a basis of the null space N(A)[tex]\subset[/tex]R^5 of the matrix
A=
1 -2 2 3 -1
-3 6 -1 1 -7
2 -4 5 8 -4
[tex]\in[/tex]M3x5(R)
and hence determine its dimension
So do i need to find the x that satisfies Ax=0 and that x is the null space? Then how do i find a basis of this null space?
