I am not able to understand the error

Hey @mishikasrvastava
Please Give custom input

import java.util.*;
public class Main {
public static void main(String args[]) {

	Scanner sc = new Scanner(System.in);
	int a = sc.nextInt();
	int b = sc.nextInt();
	int c = sc.nextInt();
	int d= b*b-(4*a*c);
	if(a==9){
		System.out.println("linear equation");
	
	if(d>0){
		double r1 = -b-Math.sqrt(d)/(2*a);
		double r2 = -b+Math.sqrt(d)/(2*a);
		System.out.println("Real but Distinct");
		if(r1>r2)
		System.out.println(r2+" "+r1);
		else
		System.out.println(r1+" "+r2);
	}
	else if(d==0){
		double r1=-b/(2*a);
		double r2=r1;
		System.out.println("Real and Equal");
	}
	else
	{ System.out.println("Imaginary");
	}
	

	


	}


}

}
My code is not passing the test cases why?

#4

Note : Print only the integer part of the roots.
Just tell me , why are you using this condition if(a==9){
System.out.println(“linear equation”);

#5

r1 and r2 and getting printed without double data type

#6

and its not a==9 but a==0 because then it will not be a quadratic equation

#7

Try for this input
1 -11 28
you are doing wrong

#8

with these input also I am unable to pass the test cases

#9

Debug your code first.
If you are not able to write a correct code. I will send you

import java.util.;
public class Main {
public static void main(String args[]) {Scanner sc = new Scanner(System.in);
int a = sc.nextInt();
int b = sc.nextInt();
int c = sc.nextInt();
int d= bb-(4ac);
if(a==9){
System.out.println(“linear equation”);

if(d>0){
	double r1 = -b-Math.sqrt(d)/(2*a);
	double r2 = -b+Math.sqrt(d)/(2*a);
	int r3 = (int)r1;
	int r4 = (int)r2;
	System.out.println("Real but Distinct");
	if(r3>r4)
	System.out.println(r4+" "+r3);
	else
	System.out.println(r3+" "+r4);
}
else if(d==0){
	double r5=-b/(2*a);
	double r6=r5;
	int r7=(int)r5;
	int r8=(int)r6;
	System.out.println("Real and Equal");
	System.out.println(r7+" "+r8);

else

#12

still one test case is not resolved

#13

correct code :
import java.util.*;

public class Main {

public static void main(String[] args) {
	Scanner sc = new Scanner(System.in);
	int a = sc.nextInt();
	int b = sc.nextInt();
	int c = sc.nextInt();
	int d = ((b * b - (4 * a * c)));
	
	if (d > 0) {
		int r1 = (int) ((-b -Math.sqrt(d)) / (2 * a));
		int r2 = (int) ((-b +Math.sqrt(d) )/ (2 * a));
		System.out.println("Real and Distinct");
		if (r1 < r2)
			System.out.println(r1 + " " + r2);
		else
			System.out.println(r2 + " " + r1);
	} else if (d == 0) {
		int r5 = -b / (2 * a);
		int r6 = r5;
		
		System.out.println("Real and Equal");
		System.out.println(r5 + " " + r6);
	} 
	else {
		System.out.println("Imaginary");
	}

}
