Overview

In this tutorial, we will write a simple C++ Program to Find Quadratic Equation Roots. The roots for the equation can be calculated as shown below:

Root 1 =

Root 2=

Program to find the roots of Quadratic Equation. Here we will discuss how to find the roots of quadratic equation where it is given that real roots exists for the given equation, using C programming language. Quadratic Equation is equation of the form ax 2 + bx + c = 0, where a, b and c are real numbers and a!= 0. The term b 2-4ac is known.

C++ Program

Enter quadratic equation in the format ax^2+bx+c: 2x^2+4x+-1 Roots of quadratic equation are: 0.000, -2.000 Other Related Programs in c C Program to calculate the Combinations and Permutations.
Next: Write a C# Sharp program to read roll no, name and marks of three subjects. Within this program to find roots of quadratic equation example, User entered Values are 10 15 -25. It means a = 10, b = 15, c = -25 and the Quadratic equation is 10x²+15x-25 = 0.

Sample Output

Root 1 := 6 Root 2 := -2 Process returned 0 (0x0) execution time : 2.083 s Press any key to continue.

Enhancements

We can further enhance the program to prompt the input values of a, b, c to the user. Right now we have to modify the code for the values.

Generate the equation string based on the values of a, b, and c and display the equation string in the output.
