What is the eccentricity of the conic `4x^(2)+9y^(2)=144`?

The eccentricity of the conic x ^(2) -4y ^(2) =1 is

The eccentricity of the conic x ^(2) -4y ^(2) =1 is

The eccentricity of the conic 4x^2-9y^2=2 is :

The eccentricity of the conic 9x^2-16y^2=144 is:

If e_(1) is the eccentricity of the conic 9x^(2)+4y^(2)=36 and e_(2) is the eccentricity of the conic 9x^(2)-4y^(2)=36 then e12-e22=2 b.e22-e12=2c.2 3

The eccentricity of the ellipse 9x^(2)+ 16y^(2)= 144 is
