Hi guys. I'm gonna right down two different problems. The first one I understand but not the second. Find the space the vectors span.

1. a=(3,5,0) b=(1,2,0) sp(a,b)=

2. c=(1,1,2) d=(1,0,1) sp(c,d) =

How do I continue to get an answer like the first question - something of the form ...(I know that's not correct, just giving an example)
