WebTo solve A x = 0, the matrix A is row reduced: Clearly, the rank of A is 2. Since A has 4 columns, the rank plus nullity theorem implies that the nullity of A is 4 − 2 = 2. Let x 3 and x 4 be the free variables. The second row of the reduced matrix gives and the first row then yields. Therefore, the vectors x in the nullspace of A are ...
