Start with a general SAS code to print out the solutions of X^2 - 5X + 6 = 0.
Write a SAS macro program to provide the solutions of aX^2 + bX + c = 0 for varied a, b, and c.

HINT: Convert the previous code as a macro program with three parameters to take values of a, b, and c.


What expected to see in the OUTPUT is

Question         Solution1              Solution2

X^2 - 5X + 6 = 0         3                        2
