In this video we illustrate how to use all of the elementary row operations on a 4x5 matrix. Once we put the matrix into reduced row echelon form, we isolate the free variables (parameters) and write every solution of the homogeneous equation in terms of the parameters. In this way, we find a basis for the null space of the matrix A or more formally a null space for the linear operator associated to A.
