# Identify the Term, Their Coefficients for the Following Expression: a 2 + B 2 − a B - Mathematics

Identify the term, their coefficients for the following expression:

$\frac{a}{2} + \frac{b}{2} - ab$

#### Solution

Definitions:
term in an algebraic expression can be a constant, a variable or a product of constants and variables separated by the signs of addition (+) or subtraction ($-$ ) . Examples: 27, x, xyz, $\frac{1}{2} x^2 yz$ etc.
The number factor of the term is called its coefficient.

The expression

$\frac{a}{2} + \frac{b}{2} - ab$ consists of three terms , i.e.,​

$\frac{a}{2}, \frac{b}{2} \text { and } - ab$

The coefficient of  $\frac{a}{2}$ is  $\frac{1}{2}$.

The coefficient of $\frac{b}{2}$ is $\frac{1}{2}$, and the coefficient of $- ab$ is $-$1.

Is there an error in this question or solution?
