Question

Identify the terms, and their coefficients for each of the​ following expressions.

Answer 1

(i) $4x^2{y}^2-4x^2{y}^2{z}^2$ + $z^2$
Terms : $4x^2{y}^2,-4x^2{y}^2{z}^2$ and $z^2$

A coefficient is a number multiplied by a variable
Coefficient of the term $4x^2{y}^2$ = 4
Coefficient of the term $-4x^2{y}^2{z}^2$ = -4
Coefficient of the term $z^2$ = 1

(ii)$\frac{x}{2}+\frac{y}{2}-xy$
Terms : $\frac{x}{2},\frac{y}{2}and-xy$

Coefficient of x =$\frac{1}{2}$
Coefficient of y = $\frac{1}{2}$
Coefficient of xy = -1
