Hello all. Firstly, I would like to sorry that I post my thread i think not in the exact segment, because I don't know really where to post it. I was wondering if someone could help me, because I am in a real trouble.

I have to solve this equation and I don't know how to do this. Just the last exercise for my full work.

i would be very grateful if you people could help me.

This is that equation:

2x^2 - 3x - 1 - 3/x + 2/x^2 = 0

Thank you in advance.
