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

Methods

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.

completeSquare(a, b, c)

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`.

getVersion()

Arguments

No arguments are required.

Return Value

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

ES6 Classes

Solver(a, b, c)

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()`.

MatrixSolver([[a, b, c], [d, e, f], ...])

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()`.
