In this program we are going to find all roots of a Quadratic Equation
public class Quadratic { public static void main(String[] args) { double a = 2.3, b = 4, c = 5.6; double root1, root2; double determinant = b * b - 4 * a * c; // condition for real and different roots if(determinant > 0) { root1 = (-b + Math.sqrt(determinant)) / (2 * a); root2 = (-b - Math.sqrt(determinant)) / (2 * a); System.out.format("root1 = %.2f and root2 = %.2f", root1 , root2); } // Condition for real and equal roots else if(determinant == 0) { root1 = root2 = -b / (2 * a); System.out.format("root1 = root2 = %.2f;", root1); } // If roots are not real else { double realPart = -b / (2 *a); double imaginaryPart = Math.sqrt(-determinant) / (2 * a); System.out.format("root1 = %.2f+%.2fi and root2 = %.2f-%.2fi", realPart, imaginaryPart, realPart, imaginaryPart); } } }Code language: JavaScript (javascript)What You get as Output , After running the program
root1 = -0.87+1.30i and root2 = -0.87-1.30i
