The eccentr A.

B.

C.

D.

Answer :

Given that we need to find the eccentricity of the ellipse 9x2 + 25y2 - 18x - 100y - 116 = 0.



9x2 + 25y2 - 18x - 100y - 116 = 0


9(x2 - 2x + 1) + 25(y2 - 4y + 4) - 225 = 0


9(x - 1)2 + 25(y - 2)2 = 225




Comparing with the standard form


Here a2>b2


eccentricity(e) =





The correct option is B
