Multiple Intersection points - 2

Calculus Level pending

Given the function: f ( x ) = e 2 x + ( 1 a x 2 ) e x a x 2 ( a R ) f(x)=e^{2x}+(1-a x^2)e^x-a x^2 \ (a \in \mathbb R) .

If equation: f ( x ) = 0 f(x)=0 has three distinct roots, find the range of a a .

The range can be expressed as ( A , + ) (A,+\infty) , submit 10000 A \lfloor 10000A \rfloor .


The answer is 18472.
