Compare Quantity A and Quantity B, using additional information centered above the two quantities if such information is given, and select one of the following four answer choices:
(A)Quantity A is greater.
(B)Quantity B is greater.
(C)The two quantities are equal.
(D)The relationship cannot be determined from the information given.
A symbol that appears more than once in a question has the same meaning throughout the question.
选项
答案
A
解析
To compare x with -2, you should first solve the equation
= 0 for x.
To solve the equation, recall that a fraction a/b is equal to 0 only if a = 0 and b ≠ 0.
So the fraction
is equal to 0 only if x(x - 2)is equal to 0 and (x + 3)(x - 4)
2
is not equal to 0. Note that the only values of x for which x(x - 2)= 0 are x = 0 and x = 2, and for these two values,(x + 3)(x-4)
2
is not equal to 0. Therefore the only values of x for which the fraction
is equal to 0 are x = 0 and x = 2. Since both 0 and 2 are greater than Quantity B, -2, the correct answer is Choice A.
This explanation uses the following strategy.
