Question

Identify the terms and the like terms in the expression.

$2n-n-4+7n$

Answer 1

Identifying the terms and the like terms:

We have given an expression $2n-n-4+7n$

We know that each part of an algebraic expression which are separated by plus sign (+) or minus sign (-) is called the term of an algebraic expression.

So, the terms in the given expression are $2n,-n,-4$ and $7n$

We know that the like terms are defined as the terms that contain the same variable which is raised to the same power.

Like terms in the given expression are: $2n,-n$ and $7n$

Hence, the terms are $2n,-n,-4$ and and like terms are $2n,-n$.and $7n$
