In this example, you will learn to find the roots of a quadratic equation in C programming. This program accepts coefficients of a quadratic equation from the user and displays the roots (both real and complex roots depending upon the discriminant).
Jul 14, 2023 · In this article, we will learn to write a C program to find the roots of the quadratic equation. Quadratic Equation is polynomial equations that have a degree of two, which implies that the highest power of the function is two.
How to write a C Program to find the Roots of a Quadratic Equation with an example? A Quadratic Equation in C can have two roots, and they depend entirely upon the discriminant. The mathematical representation of a Quadratic Equation is ax²+bx+c = 0. If discriminant > 0, then Two Distinct Real Roots will exist for this equation
Mar 20, 2024 · Given a quadratic equation in the form ax2 + bx + c, (Only the values of a, b and c are provided) the task is to find the roots of the equation. Examples: Input: a = 1, b = -2, c = 1. Output: Roots are real and same 1. Input : a = 1, b = 7, c = 12. Output: Roots are real and different. -3, -4.
Apr 13, 2016 · How to find all roots of a quadratic equation using if else in C programming. Logic to find roots of quadratic equation in C programming. Example. Input a: 8. Input b: -4. Input c: -2. Output. Root1: 0.80. Root2: -0.30. Required knowledge. Basic C programming, Relational operators, If else. Quadratic equation.
For a quadratic equation ax 2 + bx + c = 0 (a≠0), discriminant (b 2-4ac) decides the nature of roots. If it's less than Zero, the roots are imaginary. If it's greater than Zero, the roots are real. If it's Zero, the roots are equal. To calculate the square root of the discriminant, we use sqrt function of the "math.h" header file.
Sep 1, 2023 · Find roots of a quadratic equation, ax 2 +bx+c. There will be 2 roots for given quadratic equation. Analysis. Input − a,b,c values. Output − r1, r2 values. Procedure $r_{1}=\frac{-b+\sqrt{b^2-4ac}}{2a}$ $r_{2}=\frac{-b-\sqrt{b^2-4ac}}{2a}$ Design (Algorithm) Start; Read a, b, c values; Compute d = b2 4ac; if d > 0 then. r1 = b+ sqrt (d)/(2 ...
Jul 27, 2020 · To calculate the roots of a quadratic equation we use the following formula: x = − b 2 ± b 2 − 4 a c 2 a. where b 2 − 4 a c is called the discriminant. If discriminant > 0, then the equation has two distinct real roots. If discriminant = 0, then the roots of the equation are real and same.
Jun 14, 2022 · Solving Quadratic Equations in C or finding the roots of Quadratic Equations with source code, algorithm, and sample output.
Dec 18, 2022 · Start Learning. Topics Covered. Quadratic equations, expressed as ax² + bx + c = 0, involve coefficients a, b, c, where a ≠ 0. They have three types of roots—real and distinct, real and equal, or real and imaginary—determined by the discriminant (b² - 4ac).
