Question

Identify the terms, their coefficients for the following expression:

$4x^2{y}^2-4x^2{y}^2{z}^2+z^2$

• A. 4, -4, 1
• B. 4, 1,0
• C. 2,1,-1
• D. 2,3,1

Answer 1

The correct option is A 4, -4, 1

In the expression $4x^2{y}^2-4x^2{y}^2{z}^2+z^2$,
the terms are $4x^2{y}^2,-4x^2{y}^2{z}^2$ and $z^2$.
Coefficient of $x^2{y}^2$ in the tem $4x^2{y}^2$ is 4
Coefficient of $x^2{y}^2{z}^2$ in the term $-4x^2{y}^2{z}^2$ is -4
Coefficient of $z^2$ in the term $z^2$ 1
