Question

How can I make a code for solving Quadratic Iquations ?

Answer 1

make variables for a, b, and c in the equation. Then just do the arithmetic given in the quadratic equation.

like -b +- sqrt of square b -4ac all divided by 2a?

#include<stdio.h>
#include<math.h> //whenever if you want to perform higher level of mathematical operations  you should add math directive too//
float a,b,c,r1,r2;
printf("enter a,b,c ");
scanf("%f%f%f",&a.&b,&c);
r1=(-b+sqrt(b*b-4*a*c))/(2*a); //in this way we split formula, braces are mandatory
r2=(-b-sqrt(b*b-4*a*c))/(2*a);
printf("the roots of quadratic equations are %f %f", r1,r2);
return 0;
