Quadratics
https://web.stanford.edu/~surag/posts/alphazero.html
For example: ax^2 + bx + c = 0
Warning THE PARSE FUNCTION REQUIRES IT TO BE IN ax^2 + bx + c = 0 FORM
Warning THE QUADRATIC FUNCTION NEEDS TO BE FED AN A, B, AND C VALUE FOR IT TO WORK.
Functions:
quadratic(a, b, c) --> returns two polynomial answers that can be zero.
Note returns two polynomial answers that can be zero.
parse('ax^2 + bx + c') --> returns an array with a, b, and c which can be directly passed into the ^quadratic function.
Note returns an array with a, b, and c which can be directly passed into the ^quadratic function.
Example:
// source
let eq = 'x^2 - 7x + 12 = 0'
let [a, b, c] = parse(eq)
let ans = quadratic(a, b, c)
console.log(ans) // (x - 3) == 0 || (x - 4) == 0
// looking at the source is a great way to learn quadratics
