Write a Program in java that prints all real solutions to the quadratic equations ax2+bx+c=0. Read a,b,c and use the quadratic formula. If the discriminate b2-4ac is negative, display a message stating there are no real solutions.

Write a Program in java that prints all real solutions to the quadratic equations ax2+bx+c=0.

Read a,b,c and use the quadratic formula.

If the discriminate b2-4ac is negative, display a message stating there are no real solutions.

import java.util.Scanner; 

class quads{ 

 public static void main(String[] args) { 

  Scanner sc = new Scanner(System.in); 

  System.out.println("Eneter the value of a : "); 

  double a = sc.nextDouble(); 

  System.out.println("Enter the value of b : "); 

  double b = sc.nextDouble(); 

  System.out.println("Enter the value of c : "); 

  double c = sc.nextDouble(); 

  double d = b * b - 4 * a * c; 

  if (d > 0.0) { 

   double r1 = (-b + Math.pow(d, 0.5)) / (2.0 * a); 

   double r2 = (-b - Math.pow(d, 0.5)) / (2.0 * a); 

   System.out.println("The roots are " + r1 + " and " + r2); 

  } 

  else if (d == 0.0) { 

   double r1 = -b / (2.0 * a); 

   System.out.println("The root is " + r1); 

  } 

 else { 

  System.out.println("Roots are not real."); 

 } 

 sc.close(); 

 }

}

OUTPUT:

Enter the value of a :

1

Enter the value of b :

5

Enter the value of c :

2

The roots are -0.4384471871911697 and -4.561552812808831
