Add a factor method for Polynomials

[markrogoyski]

Hi @n-gram-hub,

Thank you for your interest in MathPHP.

Can you provide some more details about your feature request. It will be helpful to provide some example inputs and outputs to clarify the functionality you are requesting.

Thanks!
Mark

The first functionality is factoring polynomials in general (that is, decompose a polynomial into a product of two, or more, polynomials).

The second one is related to fractions and differences of squares, eg.

4/9x^2-9/4y^2

should produce as its first result (you can have many different ways of factoring):

(2/3x-3/2y)*(2/3x+3/2y)

If you can find another library that does this, the code could be translated to PHP. Floating point arithmetic makes this extremely difficult due to the accumulation of tiny errors.

I couldn't find any library doing this, but maybe the idea to make it work is not thinking in terms of floating point numbers
