c语言一元二次方程求解编程英语
    The quadratic equation is a second-degree polynomial equation of the form ax^2 + bx + c = 0, where a, b, and c are real numbers and a ≠ 0.
    The solutions to a quadratic equation can be found using the quadratic formula:c语言printf用法例子简单
    x = (-b ± sqrt(b^2 4ac)) / 2a.
    where sqrt() is the square root function.
    Here is a C program that implements the quadratic formula to solve a quadratic equation:
    c.
    #include <stdio.h>。
    #include <math.h>。
    int main() {。
        double a, b, c;
        double discriminant, root1, root2;
        printf("Enter the coefficients of the quadratic equation (a, b, and c): ");
        scanf("%lf %lf %lf", &a, &b, &c);
        discriminant = bb 4ac;
        if (discriminant > 0) {。
            root1 = (-b + sqrt(discriminant)) / (2a);
            root2 = (-b sqrt(discriminant)) / (2a);
            printf("The roots of the quadratic equation are: %.2lf and %.2lf\n", root1, root2);
        } else if (discriminant == 0) {。
            root1 = root2 = -b / (2a);
            printf("The quadratic equation has a single root: %.2lf\n", root1);
        } else {。
            printf("The quadratic equation has no real roots.\n");
        }。
        return 0;
    }。
    Here is an example of how to use the program:
    Enter the coefficients of the quadratic equation (a, b, and c): 1 -4 5。
    The roots of the quadratic equation are: 1.00 and 5.00。
