Description This program factors polynomials of one variable. You input the polynomials degree and then its coefficients. Then you choose wether to search for non-real roots or not. The program then searches for linear factors, and if there still remains terms of the polynomial, the program will search for a substitution: X^N, where N is any number 2, 3, 4… X^5 - X^4 + 2X^3 - 15X + 15, will be factored to: (X - 1)(X^2 - 3)(X^2 + 5). I.E. the program can find factors: ( Ax^N + B ), also when B/A is a non real number. If the substitution fails, the rest of the polynomial will be displayed together with any of the factors on the graph screen. The program can handle non real coefficients, like the polynomial: X^4 + 2iX^2 + 15, which is factored to: (X^2 - 3i)(X^2 + 5i). The program has got enhanced functions with this update.

Note! This review was written for a previous version of this file!

This program is outstanding. It surpasses every other I've tried, which is in excess of twenty. The prompts are clear, the output clear, it can deal with non-real roots and it is very modest in size. Unlike so many programs, this overtakes neither RAM nor system storage. By all means, download this program.
