I really hate to keep asking questions but I just can't figure this out, I don't know what is wrong with me but I can't figure it out. I stared at it for 5 minutes and not a thought came into my head on how to do it that actually accomplished anything.
$3x^{3/2}-9x^{1/2}+6x^{-1/2}$ I am pretty sure I can't factor this with crazy exponents but I don't know how to get rid of them and keep the problem the same. At least in any way that simplifies things.
