Question

Identify the term, their coefficients for the following expression:

 7x²yz − 5xy

Answer 1

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 

\[7 x^2 yz - 5xy\] consists of two terms, i.e.,  

\[7 x^2 yz\] and \[- 5xy\].

The coefficient of \[7 x^2 yz\] is 7 and the coefficient of  \[- 5xy\] is \[- 5\].
