public static void main(String args[]) throws Exception{
double root,root1,root2;
Scanner input=new Scanner(System.in);
System.out.println("Quadratic Equation is ax2+bx+c");
System.out.println("Enter value of a");
int a=input.nextInt();
System.out.println("Enter value of b");
int b=input.nextInt();
System.out.println("Enter value of c");
int c=input.nextInt();
int d=(b*b)-(4*a*c);
if(d>0)
{
root1=(-b + Math.sqrt(d))/(2*a);
root2=(-b - Math.sqrt(d))/(2*a);
System.out.println("Roots are distinct");
System.out.println( root1 + "," + root2);
}
else if(d==0)
{
root=(-b)/(2*a);
System.out.println("Only one root is distinct");
System.out.println(root);
}
else if(d<0)
{
System.out.println("Roots are imaginary");
}
}
}
