how to get the right solution with Nerdamer.js

Question

I am using Nerdamer.js and it works fine with the code, but when I am solving some equations, the result i get is a function instead of just numbers here is an example:

1x³+2x²+3x-4=0
if you solve this equation you will get these values:
0.7760454350285384
1.7965885235495673
-1.7965885235495673
or sometimes just the first value

but when i try to solve it with Nerdamer, I will an array of 3 objects with some informations, and the answers in each object are:

1. (-1/3)*(-146+6*sqrt(606))^(1/3)*2^(-1/3)+(5/3)*(-146+6*sqrt(606))^(-1/3)*2^(1/3)-2/3
   
2. (1/6)*((-146+6*sqrt(606))^(1/3)*2^(-1/3))^(-1)*(-5+5*i*sqrt(3))+(1/6)*(-146+6*sqrt(606))^(1/3)*(1+i*sqrt(3))*2^(-1/3)-2/3
   
3. (1/6)*((-146+6*sqrt(606))^(1/3)*2^(-1/3))^(-1)*(-5-5*i*sqrt(3))+(1/6)*(-146+6*sqrt(606))^(1/3)*(-i*sqrt(3)+1)*2^(-1/3)-2/3
   
   

and here is my code:

let nerdamer = require('nerdamer');
require('nerdamer/Algebra.js');
require('nerdamer/Calculus.js');
require('nerdamer/Solve.js');

and this is how i get the values:

var sol = nerdamer.solveEquations('1x^3+2x^2+3x-4=0');
console.log(sol[0].toString());
console.log(sol[1].toString());
console.log(sol[2].toString());

Answer 1

You need to call .evaluate() for each solution.

var sol = nerdamer
  .solveEquations('1x^3+2x^2+3x-4=0')
  .map(solution => nerdamer(solution).evaluate().text())
