Ans C.  - \frac{1}{2}

tanpopo145 · Answer

(2x+1)(x-2)=0

Case 1: 2x+1 = 0 -> x=-1/2
Case 2: x-2 = 0 -> x=2
 
-1/2 < 2 so that least number is -1/2 (C)

Abhishek009 · Answer

Objective must be to either make  (2x + 1)  = 0 Or  (x - 2) = 0  ; hence the 2 possible values are  x = -\frac{1}{2}  &  x = 2

Thus, Answer must be (C)
