Some explications about the library

The library has a resolution and factorization algorithm that works on minimum values for "a" and "b". Remember: a trinomial looks like this: "ax² + bx + c". If the values for "a", "b" and "c" are not given, the algorithm will solve this trinome by giving as default value for "a" and "b": "1" and "c": 0.

For the polinomial roots the algorithm gives approximate default values
Due to the approximation of the roots of the trinomial, the method for factoring may be obsolete

Find the roots of a trinomial

const
{
	solutions
} = require ('./trinomial-r');

const csl = console.log;

csl (solutions.OfThis ({
	a: -3,
	b: 5,
	c: 2
}));	/* S = {0 ; 2} */

Factoring the equation

const
{
	factoring
} = require ('./trinomial-r');

const csl = console.log;

csl (factoring.this ({
	a: -3,
	b: 5,
	c: 2
}));	/* -3x(x - 2) */

Find the canonical form

const
{
	canonicalForm
} = require ('./trinomial-r');

const csl = console.log;

csl (canonicalForm.OfThis ({
	a: -3,
	b: 5,
	c: 2
}));	/* -3(x - 1) + 4 */

/*
* You can choose to display alpha and beta using the optional parameters
* showAlpha: true *** default value => false
* showBeta: true *** default value => false
*/

csl (canonicalForm.OfThis ({
	a: -3,
	b: 5,
	c: 2,
	showAlpha: true,
	showBeta: true
}));

/* show ***
* alpha = 1
* beta = 4
* -3(x - 1) + 4
*/
