As we learnt

Binomial Expression

An algebraic expression consisting of only two terms is called a Binomial Expression.

eg. \left ( a+b \right ),\left ( \sqrt{x}+\frac{k}{x^{2}} \right )

 

 Now,

On expanding (a+b+c)(a+b-c)

We get \left (a+b \right )^{2}-c^2

\Rightarrow a^2+b^2-c^2+2ab

So, it is not a binomial expression
