MCQ

In any binomial expansion, the number of terms are:

A
$\geq5$
✓
$\geq2$
C
$\geq3$
D
$\geq4$

✓

Answer

Correct option: B.

$\geq2$

Bi $-$ nomial, involves summation of two terms.
Let the terms be $x$ and $y.$
Therefore a binomial expansion can be of the form, $(x + y)n.$
where $\text{n}\geq1$ If $n = 1,$ we get only two terms.If $n > 1$ where $n$ is an integer, then it gives us in total $(n + 1)$ terms.
Thus, number of terms has to be $\geq2.$
