# Basis of a null space

[SOLVED] basis of a null space

## Homework Statement

Find a basis of the null space N(A)$$\subset$$R^5 of the matrix

A=
1 -2 2 3 -1
-3 6 -1 1 -7
2 -4 5 8 -4

$$\in$$M3x5(R)

and hence determine its dimension

## The Attempt at a Solution

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?
