Problem 5. Quadratic Equation

let input = [
    '2',  // the input is always a string, so it's '3' and not 3
    '5',
    '-3'
];
let print = this.print || console.log;
let gets = this.gets || ((arr, index) => () => arr[index++])(input, 0);

let a = +gets();
let b = +gets();
let c = +gets();

let D = Math.pow(b, 2) - 4 * a * c;

let x1 = (- b -  Math.sqrt(D)) / (2 * a);
let x2 = (- b +  Math.sqrt(D)) / (2 * a);

print(x1);
print(x2);
