SOLUTION: does this equation describe an ellipse? 5y^2-18x+7=20y+3x^2-16
this is what I did
-3(x^2+6x+9) + 5(y^2-4y+4)=-23+20+(-27)
-3(x+3)^2/-30 + 5(y-2)^2/-30=-30/-30

You can put this solution on YOUR website! does this equation describe an ellipse? 5y^2-18x+7=20y+3x^2-16
-------------
You can tell it is not an ellipse because the x^2 and the y^2
terms are of different sign if you put them on the same side
of the equation.
It is the equation of a hyperbola.
