Homework Help: Dimension of solution space

  1. Nov 5, 2007 #1
    Find the dimensions of the soultion space of Ax=0,
    where A=
    1 2 5
    –1 3 1
    (A is a 2x3 matrix).

    To find the dimension you have to subtract n from rank(A)
    //n being the number of columns

    The dimension of the solution space is 1. is this correct?
