Program To Calculate Quadratic Equation

 Quadratic Equation

      Algorithm

Step1: Start

Step2: Read a, b, c values

Step3 :Compute d = b2 4ac

           if d > 0 then

          r1 = b+ sqrt (d)/(2*a)

           r2 = b sqrt(d)/(2*a)

      Otherwise if

                d = 0 then

              compute r1 = -b/2a, r2=-b/2a

                print r1,r2 values

          Otherwise if

                   d < 0 then print roots are imaginary

Step4: Stop

# include<stdio.h> # include<math.h> int main (){ float a,b,c,r1,r2,D; printf ("enter the values of a b c :\n"); scanf (" %f %f %f", &a, &b, &c); D= b*b-4*a*c; if (D>0){ r1 = -b+sqrt (D) / (2*a); r2 = -b-sqrt (D) / (2*a); printf ("The real roots = %f %f", r1, r2); } else if (D== 0){ r1 = -b/(2*a); r2 = -b/(2*a); printf ("roots are equal =%f %f", r1, r2); } else printf("Roots are imaginary"); return 0; }
