If we have W as a set of vectors of the form [5b+2c]
                                                                 | b      |
                                                                 [   c     ]
 
where b and c are arbitrary. Find vector u and v such that W=Span {u,v}.
--> Is it Two independent vectors u and v will span the set w if you have constants b &c such that bu+vc= member of W
              In the general vector int the set W we already have b and c constant in its components. Looking at pattern here 
for u and t   u={+5,-5,+1,-1}     v={+1,-1,+2,-2}?
