Awesome! Thanks for the help, I understand completely.

I have my linear algebra exam coming up but I missed the class on bases. Can anyone show me how this is solved? 2. Consider the subspace U of R4 defined by U = span{(−1, 1, 0, 2), (1, 0, 0, 1), (2,−1, 1,−1), (0, 1, 0, 3)} • Find a basis of U. • Find a basis of the orthogonal complement U.
