what is the maximum value of vx - yz . if the value of v , x , y , z have to be chosen from the set a where a ( - 3 , - 2 , - 1 , 01 , 23 )	Pick one: A) 15 B) 66 C) 25 D) 88 E) 17

Rationale: explanation : to maximize the value of vx - yz , we make yz negative and vx as maximum as possible using given value . vx − yz = ( − 3 ) 2 − ( − 3 × 2 ) vx − yz = ( − 3 ) 2 − ( − 3 × 2 ) = 15 answer : a
Answer: A
