Question

Which of the following is a binomial?

• A. $2x+7$
• B. $4x+y+2$
• C. $7y-3x+4$
• D. $3x$

Answer 1

The correct option is A

$2x+7$

An algebraic expression, which contains only two unlike terms is called a binomial.

Among the given options, 2x + 7 has two unlike terms. So it is a binomial.
$3x$ has only one term and hence, a monomial.
$4x+y+2$ and $7y-3x+4$ have three terms each, hence are trinomials.
