           Summary: Missing parentheses in problem
           Product: Problem libraries
           Version: unspecified
          Platform: PC

                    6.pg_with_problemSeed=123456
        OS/Version: Mac OS
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Library (OPL)

In the open problem library problem
/WHFreeman/Rogawski_Calculus_Early_Transcendentals_Second_Edition/3_Differentiation/3.3_Product_and_Quotient_Rules/3.3.6.pg
the line
$derivf=Compute("3*$a**2+18*$a+1");
occurs where $a is a randomly generated value which may take on negative
values.  When $a is negative, a valid student answer will be erroneously
counted wrong.  Perhaps it should be:
$derivf=Compute("3*($a)**2+18*($a)+1");
