Hi shreyashid,
This question can be solved by TESTing VALUES.
We're given the equation Y = X^2 + AX + B.
IF.. we use a simple Classic Quadratic....
A = 2
B = 1
Y = X^2 + 2X + 1
We can then go about finding the answer that yields the MINIMUM result when X = ...
Answer A: A/B = 2/1 = 2 --> 4+4+1 = +9
Answer B: -A/B = -2/1 = -2 --> 4-4+1 = +1
Answer C: -A/2 = -2/2 = -1 --> 1-2+1 = 0
Answer D: -B/2 = -1/2 -->(1/4)-1+1 = +1/4
Answer E: B/A = 1/2 --> (1/4)+1+1 = +2 1/4
From these results, we can see the minimum result:
Final Answer:
GMAT assassins aren't born, they're made,
