Quadratic Equation Solver


This JavaScript library-slash-module brings the ability of finding roots of a quadratic equation by simply requiring it :)

Example Usage

$3

``html


`

$3

`js
const { quadSolver, getVersion } = require("quadratic-solver");
console.log(getVersion());
const rootsArr = quadSolver(2, 5, -3);
rootsArr.map(root => console.log(Root: ${root}));
`

Methods

$3

#### Arguments

- a: coefficent of the squared term.
- b: coefficient of the linear term.
- c: constant with its sign.

#### Return Value

- when both roots are real: Array[2] with the roots of the equation.
- when only one root is real: Array[2] wherein the first element is the real root and the other element is a warning.
- when both roots are imaginary: Array[2] in which both elements are warnings.

Note: If a is equal to 0, quadSolverCitardauq() will be called automatically with the arguments as provided.

$3

#### Arguments

- a: coefficent of the squared term.
- b: coefficient of the linear term.
- c: constant with its sign.

#### Return Value

- when both roots are real: Array[2] with the solutions for the equation.
- when both roots are imaginary: Array[2] with both elements are in which both elements are NaN.

$3

#### Arguments

Same as quadSolver(a, b, c).

#### Return Value

Same as quadSolver(a, b, c).

$3

#### Arguments

No arguments are required.

#### Return Value

String containing name and version of the package in quadratic-solver v0.x.x format.

ES6 Classes

$3

#### Properties

- a: coefficent of the squared term; default: 2.
- b: coefficient of the linear term; default: 5.
- c: constant with its sign; default: -3.

#### Methods

- solve(): returns output of quadSolver() with properties of the instance.
- completeSquare(): returns output of completeSquare() with properties of the instance.
- versionMethod(): returns the output of getVersion().

$3

#### Properties

- matrix: array of arrays containing the coefficients of the quadratic and linear terms, followed by the constant (in that order); default: [[2, 5, -3]].

#### Methods

- solveAll(): returns output of quadSolver() for each array in an array of arrays.
- completeSquareAll(): returns output of completeSquare() for each array in an array of arrays.
- versionMethod(): returns the output of getVersion()`.
