Write a Program to find out the real roots of the quadretic equation

#include <stdio.h>

main ()

{

    float a,b,c,d,x1,x2;

    printf("Enter the coefficient of x^2 \n");

    scanf("%f",&a);

    printf("Enter the coefficient of x \n");

    scanf("%f",&b);

    printf("Enter the constant \n");

    scanf("%f",&c);

    d = (b*b)-4*a*c;

    if (d>0)

    {

        x1 = (-b + sqrt(d))/2*a;

        x2 = (-b - sqrt(d))/2*a;

        printf("One root = %f",x1);

        printf("Second root = %f",x2);

    }

    else

        printf("No real roots");

}

/*

INPUT :

Enter the coefficient of x^2

5

Enter the coefficient of x

9

Enter the constant

4

OUTPUT :

One root = -20.000000Second root = -25.000000
