write a piece of code using javascript that solves second degree equations. You pass the a, b, c parameters of: ax2 + bx + c, and the solve function will compute delta = b2 - 4a*c. Test the sign of delta, and if it's equal to zero, then display (in the console, or better, in the page) the roots of the equation.

Nice.

I would have given different prompts for each of the 3 coefficients though... As in:

//Prompt user to input values of a, b, and c...

let a = Number(prompt("Please enter the value of a..." ));
let b = Number(prompt("Please enter the value of b..." ));
let c = Number(prompt("Please enter the value of c..." ));

Etc...

Simpler and eliminates need for the second alert (i.e. the "Please confirm..." bit).

Still, neat coding.
