Homework Statement
Prove that B={(1,-1,-1),(1,0,1),(0,-1,1)} spans R^3.
(Actually, the problem asks to show that B is a basis for R^3. This would require that I prove linear independence AND that it spans R^3. The first is easy, but I'm not sure about the second.)

None
The Attempt at a Solution
I know how to prove that these vectors are linearly independent, but does that prove that B spans real space?
