Given the coefficients (constants) of a quadratic equation , i.e. **a, b, and c**; the task is to check whether roots of the equation represented by these constants are numerically equal but opposite in sign or not.

**Examples:**

Input:a = 2, b = 0, c = -1

Output:Yes

Explanation:

The given quadratic equation is

Its roots are (1, -1) which are numerically equal but opposite in sign

Input:a = 1, b = -5, c = 6

Output:No

Explanation:

The given quadratic equation is

Its roots are (2, 3) which are not numerically equal and opposite in sign

**Approach:**

To check whether roots are numerically equal but opposite in sign or not:

Quadratic Equation:

Let the roots be and

Sum of roots = =

Since roots are opposite in sign only, therforeTherefore,

, i.e, coefficient of x is 0.

Hence we have to only check if b is 0 or not, for the roots to be numerically equal but opposite in sign.

Below is the implementation of the above approach:

## C++

`// C++ program to check if roots ` `// of a Quadratic Equation are ` `// numerically equal but opposite ` `// in sign or not ` ` ` `#include <iostream> ` `using` `namespace` `std; ` ` ` `// Function to find the required answer ` `void` `checkSolution(` `int` `a, ` `int` `b, ` `int` `c) ` `{ ` ` ` `if` `(b == 0) ` ` ` `cout << ` `"Yes"` `; ` ` ` `else` ` ` `cout << ` `"No"` `; ` `} ` ` ` `// Driver code ` `int` `main() ` `{ ` ` ` `int` `a = 2, b = 0, c = 2; ` ` ` ` ` `checkSolution(a, b, c); ` ` ` ` ` `return` `0; ` `} ` |
