Write a java Program to find the Quadratic Equation roots

import java.lang.*;
import java.io.*;
class Quadratic
{
    public static void main(String args[])
    {
        double b=12.1,a=2.35,c=12.50,dis,root1,root2;
        dis=(b*b)-(4*a*c);
        root1=(-b+Math.sqrt(dis)/2*a);
        root2=(-b-Math.sqrt(dis)/2*a);
        if(root1<=0 && root2<=0)
        {
            System.out.println("Roots are imaginary");
        }
        else
        {
        System.out.println("The result is:"+root1);
        System.out.println("The result is:"+root2);
        }
    }
}
