The reasoning given is correct but one fact that has been missed is that what if the answer is 0. Then (x – 4)(x – 3)(x + 2)(x + 1) = 0 which will deny the question stem. Yes, 0 is positive but that is not asked in the question stem. In the question stem, it is asked whether the equation is "greater than 0" or not. Please tell me if I'm thinking on the right terms or not.
