JEE MainMathematicsEllipseMCQ+4 / −1
Let the length of a latus rectum of an ellipse x2a2+y2b2=1\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1a2x2​+b2y2​=1 be 10. If its eccentricity is the minimum value of the function f(t)=t2+t+1112f(t) = t^2 + t + \frac{11}{12}f(t)=t2+t+1211​, t∈Rt \in \mathbb{R}t∈R, then a2+b2a^2 + b^2a2+b2 is equal to :
  1. A
    115
  2. B
    120
  3. C
    125
