C++ Program to Find All Roots of a Quadratic Equation This program accepts coefficients of a quadratic equation from the user and displays the roots (both real and complex roots depending upon the determinant). To understand this example, you should have the knowledge of following C++ programming topics: C++ if, if...else and Nested if...else For a quadratic equation ax 2 +bx+c = 0 (where a, b and c are coefficients), it's roots is given by following the formula. The term b 2 -4ac is known as the determinant of a quadratic equation. The determinant tells the nature of the roots. If determinant is greater than 0, the roots are real and different. If determinant is equal to 0, the roots are real and equal. If determinant is less than 0, the roots are complex and different. Example: Roots of a Quadratic Equation #include <iostream> #include <cmath> using namespace std ; int main () { float a , b ,
