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.
