1. Apr 13, 2016 Logic to find all roots of a quadratic equation. Based on the above formula let us write step by step descriptive logic to find roots of a quadratic equation. Input coefficients of quadratic equation from user. Store it in some variable say a, b and c. Find discriminant of the given equation, using formula discriminant = (b.b) - (4.a.c).
2. Apr 13, 2016 Input coefficients of quadratic equation. Store it in some variable say a, b and c. Find discriminant of given equation using formula i.e. Discriminant = (b. b) - (4. a. c). You can also use pow function to find square of b. Compute the roots based on the nature of discriminant.

The Quadratic Formula in C Home. Programming Forum Software Development Forum Discussion / Question rebellion346 Light Poster. So I managed to get everything working right except for one thing, when I enter the following input: a = 2 b = 2. Hi i want the user enter the Quadratic equation like that (ax^2+bx+c) 0 0.

There are three cases −

b² < 4*a*c - The roots are not real i.e. they are complex
