Given that (n-2)(n-3)=0, the solutions to the equation are n = 2 or 3.
When n = 2:
Quantity A = −2(2)−1 = -5
Quantity B = 2(2)+1 = 5
Since 5>-5, Quantity B is greater
When n = 3:
Quantity A = −2(3)−1 = -7
Quantity B = 2(3)+1 = 7
Since 7>-7, Quantity B is greater
Quantity B is greater for both solutions of n, so the answer is B.

\( (n – 2) (n – 3) = 0\)
=> n = 2 or 3
Quantity A
-2n - 1 = -(2n + 1) = -(Quantity B)
Since, n is positive so Quantity B which is positive will always be greater than Quantity A which is negative!
So, Answer will be B
Hope it helps!

Calculation for both the values of n below
Quantity A
For n = 2, -2n-1 = -2*2 - 1 = -5
For n = 3, -2n - 1 = -2*3 - 1 = -7
Quantity B = 5 and 7 respectively
