<PRE><B>Question 1014014</B>
-20 + 31x - 12x^2 
------
-(12x^2 - 31x +20)
----
discriminant:: b^2 - 4ac
------
b^2 - 4ac = 31^2 - 4*12*20 = -479
-------
Since the discriminant is negative the zeroes of 
this algebraic form are complex numbers.
-----
The Form is considered to be prime because is 
has no Real Number zeroes.
