program to find the roots of a quadratic equation..

Answer / gogol

#include<stdio.h>
#include<conio.h>
#include<math.h>
void main()
{
float a,b,c,x1,x2,disc,disc1;
clrscr();
printf("Let the quadratic equation is of the form:
a(x^2)+b(x)+c=0; Enter the values of the coefficients:\n");
printf("Enter the value of a: ");
scanf("%f",&a);
printf("Enter the value of b: ");
scanf("%f",&b);
printf("Enter the value of c: ");
scanf("%f",&c);
disc=b*b-4*a*c;
if(disc>0)
{
x1=(-b+sqrt(disc))/(2*a);
x2=(-b-sqrt(disc))/(2*a);
printf("The roots are distinct and they are: %3.3f and
%3.3f",x1,x2);
}
if(disc==0)
{
printf("The roots are equal and it is: %3.3f",-b/(2*a));
}
if(disc<0)
{
disc1=-disc;
x1=-b/(2*a);
x2=sqrt(disc1)/(2*a);
printf("The roots are complex and they are: %3.3f+%3.3fi
and %3.3f-%3.3fi",x1,x2,x1,x2);
