Ok, but for this question, as we're testing values, if the value for the expression in A is minimized by one value for x and the value for the expression in B is minimized by a different value for x, those are the values we "go with" when picking an answer (even though they are different) because we are looking for the minimum possible values for A and B not a comparison of the values of A and B when utilizing the same value for x. That seems to be what the answer explanation is saying, just wanted to confirm that.
