I used the solve funtion (MENU + A +F3 )

 

I need to know the solution for this equation:
 

1/2*0,5*10^3*(1,82-4000X)^2=X

 

The expected solution should be:

2.203E-4

 

9.939E-4

 

The result given by my fx9860 is 2.203E-4. It is missing the other zero (9.939E-4).

 

thanks for your help

I solved this equation: 250×(1,82-4000*x)2=x
