# x+y=3, xy=3 Find x^3+y^3. Am I doing it right? Watch

1. I squared to give . I then took away to give . Then multiplied that by to give which equals then take away to finally get but it seems a bit easy. I don't have answers either so I can't tell. Thanks!

I squared to give . <--------That 3 is wrong.

It's easier to say y=3-x so x(3-x)=3 and solve that. There are no real solutions by the way.
