**Question 67 : Write a program in Java to find the solution of a quadratic equation by taking the inputs of a,b,c from the user.**

**Java Program :**

import java.io.*;

class quadratic

{

static void main()throws IOException

{

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

int a,b,c;

double d,e;

System.out.println("The format of a quadratic equation is given as follows : ");

System.out.println("\nax2 + bx + c = 0");

System.out.println("\nEnter values for a,b,c as follows : ");

System.out.print("\na = ");

a=Integer.parseInt(br.readLine());

System.out.print("\nb = ");

b=Integer.parseInt(br.readLine());

System.out.print("\nc = ");

c=Integer.parseInt(br.readLine());

d=((-1*b)+java.lang.Math.sqrt((b*b)-(4*a*c)))/(2*a);

e=((-1*b)-java.lang.Math.sqrt((b*b)-(4*a*c)))/(2*a);

System.out.print("\nEquation : "+a+"x2");

if(b<0)

System.out.print(b+"x");

else

System.out.print("+"+b+"x");

if(c<0)

System.out.print(c);

else

System.out.print("+"+c);

System.out.print(" = 0");

System.out.println("\n\nSolution : x = ( "+d+" , "+e+" )");

}

}
