What is the number of terms in the given expression?

A binomial expansion

(a + b)ⁿ

contains n + 1 terms unless some terms merge after simplification.

Here,

(x² + 2/x)¹¹

has

11 + 1 = 12

terms.

Checking the powers:

22, 19, 16, 13, 10, 7, 4, 1, −2, −5, −8, −11

All are distinct.

Hence no terms merge.

Answer

12 (Option A) ✅
