Please help Linear algebra problem about parametric vectorform.
Given A = [ ] and b = [-1 1 2]. Describe in parametric vector form the solution(s) of Ax = b. Do the columns of A span R3? Explain. Let a1 = [1 3 -1], a2 = [-5 -8 2], and b = [3 -5 3]. Determine whether b is in the Span{a1, a2}. If yes, write the dependency relation. That is, find weights x1 and x2, that describe b as a linear combination of a1 and a2.
