1. The problem statement, all variables and given/known data Find null space of A, NS(A) and sketch NS(A) in R2 or R3. A = [1 3 2; 2 6 4] 2. Relevant equations AX = 0 3. The attempt at a solution I know the second row is twice the first one. I tried to solve for x1, x2 and x3 putting everything in the form of AX =0. I did not get a confident answer to sketch.
