Determine whether the set S={x[tex]^{2}[/tex]-2x,x[tex]^{3}[/tex]+8,x[tex]^{3}[/tex]-x[tex]^{2}[/tex],x[tex]^{2}[/tex]-4} spans P3
for example, if i had S={(123),(234),(345)} and asked to determin if this set spans R[tex]^{3}[/tex], then I would write these components as a matrix and then reduce to echelon form. From there Id be able to tell if this set spans R[tex]^{3}[/tex].
But for this problem I don't know how to approach it. Its the first time i see a problem like this.
