Question

Write a program in Java incorporating the quadratic equation in programming language.

Answer 1

Answer:

INPUT

import java.util.Scanner; public class RootsOfQuadraticEquation {    public static void main(String args[]){       double secondRoot = 0, firstRoot = 0;       Scanner sc = new Scanner(System.in);       System.out.println("Enter 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 determinant = (b*b)-(4*a*c);       double sqrt = Math.sqrt(determinant);       if(determinant>0){          firstRoot = (-b + sqrt)/(2*a);          secondRoot = (-b - sqrt)/(2*a);          System.out.println("Roots are :: "+ firstRoot +" and "+secondRoot);       }else if(determinant == 0){          System.out.println("Root is :: "+(-b + sqrt)/(2*a));       }    } }

Explanation:

OUTPUT

Enter the value of a :: 15 Enter the value of b :: 68 Enter the value of c :: 3 Roots are :: -0.044555558333472335 and -4.488777774999861.
