Computing zeroes (solutions) of a mathematical equation in 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.
Example
The code for this will be −
const coeff = [1, 12, 3];
const findRoots = co => {
const [a, b, c] = co;
const discriminant = (b * b) - 4 * a * c;
// non real roots
if(discriminant < 0){
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(coeff));Output
The output in the console −
[ -0.2554373534619714, -11.744562646538029 ]
