    Linear Combination and Span? [Solved]

    How would you show that the vectors (1,1,0) (1,0,1) and (0,1,1) generate F^3?

    Do you simply put them in the matrix and solve the matrix or?

    Since F^3 (whatever that is) has dimension three it means if you can show {(1,1,0),(1,0,1),(0,1,1)} are linearly independent it would mean they must spam the space.
    Now say a(1,1,0)+b(1,0,1)+c(0,1,1) = (0,0,0).
    This means,
    a+b = 0
    a+c=0
    b+c=0
    Now argue that a=b=c=0.
