C - Program (Sequence) - Quadratic Equation


4.Write a program to solve the quadratic equation ax ^ 2 + bx + c = 0, where x = (√-b + -b ^ 2-4ac) / 2a.

 #include <stdio.h>
#include <conio.h>
#include <math.h>
void main ()
{
  int a, b, c;
  float x, y;
  printf ("Enter the value of a, b & c =");
  scanf ("% d% d% d", & a, & b, & c);
  x = pow ((- b + b * b-4 * a * c), 0.5) / 2 * a;
  y = pow ((- bb * b-4 * a * c), 0.5) / 2 * a;
  printf ("value of x =% f", x);
  printf ("value of y =% f", y);
  getch ();

Generally, pr
