6. Consider the system Ax=b, where A=???1231?2463?0?3?31?1012??253?1????,b=???b1?b2?b3?b4?????. (a) Find conditions on the values of b so that rank(A)=rank[A?b]. (b) If a solution exists, find the complete solution x=xp?+xn? of Ax=b when b=(4,6,10,6). (c) If a solution exists, find the complete solution x=xp?+xn? of Ax=b when b=(?2,2,2,?2).
