Make a program in C# that find the value of X by using quadratic formula.

CODE:

using System;

usingSystem.Collections.Generic;

usingSystem.Linq;

usingSystem.Text;

namespace ConsoleApplication4

{

classProgram

    {

staticvoid Main(string[] args)

        {

double a, b, c, y,X1, X2;

Console.WriteLine("please enter a");

            a = Convert.ToDouble(Console.ReadLine());

Console.WriteLine("please enter b");

            b = Convert.ToDouble(Console.ReadLine());

Console.WriteLine("please enter c");

            c = Convert.ToDouble(Console.ReadLine());

            y = Math.Sqrt((b * b) - (4 * a * c));

            X1 = ((-1) * (b) + y) / (2 * a);

            X2 = ((-1) * (b) - y) / (2 * a);

Console.WriteLine("the value of X1 is {0}",X1);

Console.WriteLine("the value of X2 is {0}", X2);

        }

    }

}

 OUTPUT:

ALGORITHM:

• ·         Start:
• ·         Initializing: double a, b, c, y, X1, X2,
• ·         Output: please enter a
• ·         Set a: Taking input from the user
• ·         Output: please enter b
• ·         Set b:Taking input from the user
• ·         Output: please enter c
• ·         Set c: Taking input from the user
• ·         Set y: square root of {(b * b) - (4 * a * c)}
• ·         Set X1: {(-1) * (b) + y} / (2 * a)
• ·         Set X2: {(-1) * (b) - y} / (2 * a)
• ·         Output: Result
• ·         End.
