quadratic problem solution c++

To solve a quadratic problem in C++, you can use the quadratic formula. The formula is as follows:

x = (-b ± √(b^2 - 4ac)) / (2a)

Here's a step-by-step explanation of how to solve a quadratic problem using C++:

1. Declare and initialize the variables for the coefficients a, b, and c of the quadratic equation.

double a, b, c;
// Initialize the values of a, b, and c
a = 2.0;
b = -5.0;
c = 3.0;

1. Calculate the discriminant (b^2 - 4ac) using the values of a, b, and c.

double discriminant = b  b - 4  a * c;

1. Check the value of the discriminant to determine the nature of the roots.
2. If the discriminant is greater than 0, the equation has two real and distinct roots.
3. If the discriminant is equal to 0, the equation has two real and identical roots.
4. If the discriminant is less than 0, the equation has two complex roots.

if (discriminant > 0) {
    // Two real and distinct roots
    double root1 = (-b + sqrt(discriminant)) / (2 * a);
    double root2 = (-b - sqrt(discriminant)) / (2 * a);
    // Print the roots
    cout << "Root 1: " << root1 << endl;
    cout << "Root 2: " << root2 << endl;
} else if (discriminant == 0) {
    // Two real and identical roots
    double root = -b / (2 * a);
    // Print the root
    cout << "Root: " << root << endl;
} else {
    // Two complex roots
    double realPart = -b / (2 * a);
    double imaginaryPart = sqrt(-discriminant) / (2 * a);
    // Print the roots
    cout << "Root 1: " << realPart << " + " << imaginaryPart << "i" << endl;
    cout << "Root 2: " << realPart << " - " << imaginaryPart << "i" << endl;
}

This is a basic example of how to solve a quadratic problem in C++. You can customize it based on your specific needs by inputting the values of a, b, and c from the user or any other source.
