उत्तर
Definitions:
A 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.
