Webthese two vector equations using the “basic matrix trick” gives us: −3a1 +a2 +a3 = 0 and 2a1 −2a2 +a4 = 0. We can use these to solve for the free columns in terms of the leading columns, a3 = 3a1 −a2 and a4 = −2a1 +2a2. Thus the column space is spanned by the set {a1, a2}. (a1 and a2 are in boldface in our matrix A above in (1).) WebSep 17, 2024 · The parametric form for the general solution is. (x, y, z) = (1 − y − z, y, z) for any values of y and z.
