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).
