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
\[x^2 + x + 1\] consists of three terms , i.e.,
\[x^2\], x and 1.
The coefficient of each term is 1.
