C Program To Find Quadratic Equation

C Program to find the roots of quadratic equation. Quadratic equations are the polynomial equation with degree 2. It is represented as ax 2 + bx +c = 0, where a, b and c are the coefficient variable of the equation. The universal rule of quadratic equation defines that the value of 'a' cannot be zero, and the value of x is used to find the.


I have given here a C# program to solve any Quadratic Equation. Quadratic equation is a second order of polynomial equation in a single variable. 
x = [ -b +/- sqrt(b^2 - 4ac) ] / 2a

 We have to find the value of (b*b - 4*a*c). 
C if.else Statement The standard form of a quadratic equation is: ax 2 + bx + c = 0, where a, b and c are real numbers and a!= 0 The term b 2 -4ac is known as the discriminant of a quadratic equation.
Here we will a write a program to solve quadratic equation in C programming language. Let’s first understand how to solve a quadratic equation: Let’s take the quadratic equation as: ax²+bx+c=0. How program works: Take the values for a, b and c (double type). If, a = b = 0 then invalid equation; if b² -4ac.
When it is greater than Zero, we will get two Real Solutions.
When it is equal to zero, we will get one Real Solution.
When it is less than Zero, we will get two Imaginary Solutions.
When there is an imaginary solutions, we have to use the factor i to represent imaginary part as it is a complex number.

Let’s take the quadratic equation as:ax²+bx+c=0
How program works:Take the values for a, b and c (double type).
if, a = b = 0 then invalid equation
if b² -4ac < 0 then the real roots
if b² -4ac > 0 , x1= (-b+√(b² -4ac))/2a , x1= (-b -√(b² -4ac))/2a
The C++ function for √x is sqrt(x).
Include math.h for using the sqrt() function.
