Find the vertices of the ellipse 144x^2 + 169y^2 + 864x - 23760 = 0.
----------------------
144(x^2+6x+9) + 169y^2 = 23760+144*9
-----
144(x+3)^2 + 169(y-0)^2 = 25056
-----
(x+3)^2/174 + (y-0)^2/148.26 = 1
-----------------------------
Center:: (3,0)
semi-major axis:: sqrt(174)
semi-minor axis:: sqrt(148.26)
-----
Left-vertex:: (3-sqrt(174),0)
Right-vertex:: (3+sqrt(174),0)
------------
