How do you write a program that will solve the quadratic equationax2+bx=c=0

Hi, the general factorization formula, which will allow us to find the values for X of any polynomial of type Ах²⁺Вх+С.

Explanation:

This is one example taken from the C language:

int main()

{

   int a,b,c,d;

   float x,y;

   printf("Input  a: ");

   scanf("%d",&a);

   while (a == 0) {

       printf("Input a: ");

       scanf("%d",&a);

   }

   printf("Input b: ");

   scanf("%d",&b);

   printf("Input c: ");

   scanf("%d",&c);

   d = b*b-4*a*c;

   if (d > 0) {

       x = (-b+sqrt(d))/(2*a);

       y = (-b-sqrt(d))/(2*a);

       printf("x1 = %.2f\n",x);

       printf("x2 = %.2f\n",y);

   }

   else if (d == 0) {

       x = (-b)/(2*a);

       printf("x1 = %.2f\n",x);

   }

   else

       printf("The equation don't have solution.");

   return 0;

}
