Question

Can you indicate what will go in the command window and what will go in the script window. Thanks
The roots of a quadratic equation ax2 bx given by the formula c 0 are 4 ac 2a write a function that take as input the coefficients a, b,c and returns as output the roots x1,x2 o the quadratic equation. Let x1 be the smaller of the two roots. -If a is zero, print a warning message user of the situation. But, then solve the linear informing the equation for the single root and set x2 NaN If b2 4ac is negative, print a warning message informing the user of the situation. But, then solve the equation anyways to find and return the complex roots. If b 4ac is zero, set x2 equal to the unique root x1. If any of a, b, c are not scalar numbers, print an error message informing the user of the situation and set x x2 NaN

import java.util.InputMismatchException;
import java.util.Scanner;
public class QuadEquation
{
public static void main(String[] args)
{
   //Declared required variables for quadratic equation
int a, b, c;
double x1, x2, d;

System.out.println("Enter values for quadratic equation as :ax^2 + bx + c");
  
System.out.print("Enter value of a:");
a = sc.nextInt();
  
System.out.print("Enter value of b:");

System.out.print("Enter value of c:");
c = sc.nextInt();
  
System.out.println("Given quadratic equation:"+a+"x^2 + "+b+"x + "+c);
  
  
//Calculated value of d
d = b * b - 4 * a * c;
  
// Warning for a=0

System.out.println

}
  
// If scalar values are entered
}
catch(InputMismatchException e)
{
   System.out.println("You have enterd non scalar value of coefficient");
   System.out.println("Root1= NaN and Root2= NaN");
}
}
