I was practicing for an upcoming exam where I came across this question (in image). I don't have a majorly specific question -- I genuinely just didn't know where to start (though I suspect it may have to do with Gram Schmidt since only v2 is given) with this question and would love an explanation that's more in detail than the one in the image below:
