(1) n(n -1)(n - 2 ) = 0
(2) n^2 + n - 6 = 0

IMO:E
Stmt 1 : -- we will get 3 values of N (degree 3). The values are -- 0, 1, & 2 [NOT SUFFICIENT]

Stmt 2: -- we will get 2 values of N (quadratic equation). The values are: 2, & -3. [ NOT SUFFICIENT]

Combine both statement we have the common value of n = 2. [ Sufficient]

Option C
