Question

Identify the numerical coefficients of terms (other than constants) in the following expressions: $x+2xy+3y$

Answer 1

Identify the numerical coefficients of the terms

The numerical coefficient of a term is the numerical factor of the term. It is a constant in the expression.

Given expression is $x+2xy+3y$.

The terms (other than the constant) in the expression are: $x$, $2xy$ and $3y$.

Their numerical coefficients are:

$$\begin{gathered} x\to 1 \\ 2xy\to 2 \\ 3y\to 3 \end{gathered}$$

Therefore, the numerical coefficients of the terms $x$, $2xy$ and $3y$ are $1$, $2$ and $3$ respectively.

Note:

When the coefficient is $1$, it is omitted in writing the expression.
