Question

Which of the following is a monomial?

• A. $4x^2$
• B. $4x^2+2x^2$
• C. $x^3+4x^2+2$
• D. $4x^2+4x+2$

Answer 1

The correct option is A $4x^2$

A polynomial expression that contains only one term is called a monomial.

$4x^2+4x+2\text{has three terms.}$
$4x^2\text{has only one term.}$
$4x^2+2x^2\text{has two terms.}$
$x^3+4x^2+2\text{has two terms.}$
