Hey, I was wondering if any of you could look at this problem for me, to be specific, problem 2c (https://234ae6be-a-62cb3a1a-s-sites....attredirects=0)

is the problem I am having trouble on. I understand how Gram -Schmidt works, I am just wondering if I am doing something incorrectly because I've been working on this problem for the last couple hours and been turning up with ridiculous answers. Note my professor does not allow the use of calculators so I am surprised to these ridiculous answers for a final exam review.
