If a data sufficiency Q asks: What is the value of integer x? and one of the statement stems (say statement stem 2) has a quadratic equation which yields two values for x (both integers); then on that basis can statement 2 be said to be insufficient on its own?
To me it seems the "value" of x (though expressed in singular) should be considered to be satisfied even if a quadratic equation is involved which yields two integer values... But Bin 3, "Cracking the GMAT 2010 edition", Q. 26 reasons otherwise and considers statement 2 insufficient. Is this the way to go on the GMAT? Thanks!
