Question

Which of the following is/are monomial, or can be made monomial?

• A. $(4x+2)$
• B. $4+6$
• C. $4\times 2+3$
• D. $2x+3x$

Answer 1

Answer: (B), (C), (D)

$2x+3x$

$\underset{–}{\text{Monomial:}}$
An algebraic expression consisting of only one non-zero term is called a monomial
For example: $5p,7,6x{y}^3$ etc.

Let's have a look at each option separately:
$\bullet \underset{–}{(4x+2):}$
We can see that there are two terms in this expression, $4x$ and $2,$ that cannot be merged. As a result, it is binomial not a monomial.

$\bullet \underset{–}{4+6:}$
It can be simplified to a single term as $4+6=10.$ Therefore, it is a monomial.

$\bullet \underset{–}{4\times 2+3:}$
It can be simplified to a single term as $4\times 2+3=8+3=11.$ Therefore, it is a monomial.

$\bullet \underset{–}{2x+3x:}$
It can be simplified to a single term as $2x+3x=5x.$ Therefore, it is a monomial.
