 2007-12-09, 16:56 #2 wblipp     "William" May 2003 New Haven 1001010000012 Posts There is information about how to calculate algebraic factors in the FAQ. Most of the incompletly factored algebraic factors show up on the Planner page. http://elevensmooth.com/ElevenPlan.html This page follows Will Edgington's convention that 2^n+1 is covered under M(2n).

Now, why was your question silly?

You still need to think some more. Then you will (probably) realise why your question is silly.

Heavy hints: factoring programs exist to factor small integers and they are also trivial to write; the exponents in algebraic factors will be factors of the original exponent.

Yes, there are.

Do you want EVERYTHING handed to you??? You need to go learn
some elementary mathematics.

Why not learn something by writing such a program yourself????
