Synthetic Division on the HP48
Date: 09/11/97 at 17:49:46 From: Gary Bacchus Subject: Synthetic Division on the HP48 I read that you have a program for synthetic division for the HP48. I was wondering if you could send it to me. Thank you.

It takes as inputs two things: in level 1 the number c you wish to test, and in level 2 the polynomial, in the form [1 2 1], which would stand for 1x^2+2x+1. The program returns [1 2 1] in level 2, for use again if needed, and the coefficients of the division in level 1, for deletion if wanted. If level 1 of the input contains 'X' the program returns the factored form of the polynomial (which is the remainder). << -> P C << P SIZE OBJ-> DROP -> M << 0 P 1 (the symbol "O" here is a zero) 1 M 1 - START GETI 4 ROLL + DUP 4 ROLLD C * 3 ROLLD NEXT GET + M C TYPE 6 IF (unequal sign goes here) THEN ->ARRY P SWAP ELSE ROLLD M 1 - DROPN P SWAP END >> >> >> -Doctor Jerry, The Math Forum Check out our web site! http://mathforum.org/dr.math/
