If e1 and e2 are respectively the eccentricities of the ellipse x218+

1.	If e1 and e2 are respectively the eccentricities of the ellipse x218+y24=1 and the hyperbola x29+y24=1,then write the value of 2e21+e22.
Answer» If $e_{1}$ and $e_{2}$ are respectively the eccentricities of the ellipse $\frac{x^{2}}{18} + \frac{y^{2}}{4} = 1$ and the hyperbola $\frac{x^{2}}{9} + \frac{y^{2}}{4} = 1$ ,then write the value of $2 e_{1}^{2} + e_{2}^{2} .$

Answer»

If $e_{1}$ and $e_{2}$ are respectively the eccentricities of the ellipse $\frac{x^{2}}{18} + \frac{y^{2}}{4} = 1$

and the hyperbola $\frac{x^{2}}{9} + \frac{y^{2}}{4} = 1$ ,then

write the value of $2 e_{1}^{2} + e_{2}^{2} .$
