Q. Solve quadratic equation ?

THE OUTPUT WOULD BE

 
#include<stdio.h>
#include<conio.h>
#include<math.h>
  void main( )
  {    clrscr( );
        float a,b,c,D,X1,X2;
        printf("The Standard form of equation are : aX^2+bX+c=0");
        printf("\nEnter the value of a,b,c=\n");
        scanf("\t%f\t%f\t%f",&a,&b,&c);
        D=(b*b-4*a*c);
        if(D>0)
        { X1=(-b+sqrt(D))/2*a;
           X2=(-b-sqrt(D))/2*a;
           printf("Unequal roots\n");
           printf("The value of X1=%.2f",X1);
           printf("\tThe value of X2=%.2f",X2);
        }
        else if(D==0)
        { X1=(-b+sqrt(D))/2*a;
           X2=(-b-sqrt(D))/2*a;
           printf("Equal roots\n");
           printf("The value of X1=%.2f",X1);
           printf("\tThe value of X2=%.2f",X2);
        }
        else
        { printf("Imaginary roots\n");
        }
        getch( );
}
