Access: Arithixietic, RiM)
POLYNOMIAL
Input: Level 2/Argiiment 1: The expression coiTesponding to a
in the equation.
Level 1/Argiiment 2: The expression corresponding to b
in the equation.
Output: Level 3/Item 1: The result corresponding to c in the
equation.
Level 2/Item 2: The result corresponding to u in the
equation.
Level 1/ltem 3: The result corresponding to v in the
equation.
Flags: Exact mode must be set (flag -105 clear).
Numeric mode must not be set (flag -03 clear).
Example: Find the polynomials for u, v, and c, where c is the
greatest common divisor of a and b such that:
u(x + 1) + v{x - 1) = c
Command: E G C D ( X ^ 2 + 1 , X - 1 )
Result: { 2 , 1 , - { X + D }
