If and , what is the least value of possible?

A. -1/100

B. -1/50

C. -1/36

D. -1/18

E. -1/6

For Detailed Answers:

To get the least value of , which obviously will be negative, try to maximize absolute value of , as more is the absolute value of a negative number "more" negative it is (the smallest it is).

To maximize pick largest absolute values possible for and : . Notice that: -1/18<-1/36<-1/50<-1/100, so -1/100 is the largest number and -1/18 is the smallest number (we cannot obtain -1/6 from x^2*y or else it would be the correct answer).

Answer: D.
