Lesson: FOIL Method for Expanding

Comment on FOIL Method for Expanding

For the last ques from Math Rev...

Is x^2 > y^2?

(1) x + y = 2
(2) x > y

How is the OA C? my explanation:

-Assume 1 and 2 are not suff on their own
x= 2, y= 0 (satisfying 1 and 2) --> Yes, 4 > 0
x= 2, y= -4 (satisfying 1 and 2) --> No, 4 is not greater than 16

Shouldn't the answer be E???

x= 2, y= -4 does not satisfy statement 1
