Answer 187449 by richwmiller(1774) About Me on 2010-01-09 17:12:13:
You can put this solution on YOUR website!
x = -2 sqrt(3), y = 2 (9+sqrt(3)) x=-3.4641, y=21.4641
x = 2 sqrt(3), y = -2 (sqrt(3)-9) x=3.4641, y=14.5359
It is a line crossing a parabola.
Please explain this in detail thank you so much
