Re: Any expert for polynomial roots here? Message #18 Posted by Ángel Martin on 11 Nov 2011, 2:12 a.m., in response to message #17 by Ángel Martin
and here are the roots found by the program for Valentin´s second example:
x^20+10 x^19+55 x^18+210 x^17+615 x^16+1452 x^15+2850 x^14+
4740 x^13+6765 x^12+8350 x^11+8953 x^10+8350 x^9+6765 x^8+
4740 x^7+2850 x^6+1452 x^5+615 x^4+210 x^3+55 x^2+10 x+1 = 0

execution time on V41: about 8 seconds (TURBO mode of course). It´s included in the 41Z module, so just load the image MOD file and turn it loose.
Write or wrong? Easy enough to check ...
