Question

Identify the terms, their coefficients for the following expression:

$5xy{z}^2-3zy$

• A. Coefficient of $xy{z}^2$ is 5 and that of $zy$ is -3
• B. Coefficient of $xy{z}^2$ is -5 and that of $zy$ is 3
• C. Coefficient of $xy{z}^2$ is 0 and that of $zy$ is 0
• D. Coefficient of $xy{z}^2$ is 3 and that of $zy$ is 5

Answer 1

The correct option is A Coefficient of $xy{z}^2$ is 5 and that of $zy$ is -3

A coefficient is a multiplicative factor in some term of a polynomial, a series or any expression; it is usually a number, but can be any expression. In the latter case, the variables appearing in the coefficients are often called parameters, and must be clearly distinguished from the other variables.
Coffecient of $xy{z}^2$ is $5$ and $zy$ is $-3$.
