# Write the coefficient of x in each term of the following expressions: (a) $2 a^{2}-x a$ (b) $3 x^{2}-x+y$

Given :

The given expressions are (a) $2 a^{2}-x a$ and (b) $3 x^{2}-x+y$

To do :

We have to find the coefficient of 'x' in the given expressions.

Solution :

Coefficient :

A coefficient is the numerical part of a product of numbers and variables.

(a) $2 a^{2}-x a$

Here, $-a$ is the coefficient of x.

(b) $3 x^{2}-x+y$

Here, $-1$ is the coefficient of x.
