# Finding roots of a quadratic equation – JavaScript

We are required to write a JavaScript function that takes in three numbers (representing the coefficient of quadratic term, coefficient of linear term and the constant respectively in a quadratic quadratic).

And we are required to find the roots, (if they are real roots) otherwise we have to return false. Let's write the code for this function

## Example

Following is the code −

const coefficients = [3, 12, 2];
const findRoots = co => {
const [a, b, c] = co;
const discriminant = (b * b) - 4 * a * c;
if(discriminant < 0){
// the roots are non-real roots
return false;
};
const d = Math.sqrt(discriminant);
const x1 = (d - b) / (2 * a);
const x2 = ((d + b) * -1) / (2 * a);
return [x1, x2];
};
console.log(findRoots(coefficients));

## Output

The output in the console −

[ -0.17425814164944628, -3.825741858350554 ]
