Question

Identify the non-constant term in the algebraic expression $3x^2-4$ and get its coefficient.

• A. Term: $3x^2$
  Coefficient: $4$
• B. Term: $3x^2$
  Coefficient: $-4$
• C. Term: $3x^2$
  Coefficient: $3$
• D. Term: $3x^2$
  Coefficient: $2$

Answer 1

The correct option is C Term: $3x^2$

Coefficient: $3$
$\underset{–}{\text{Given:}}$
An algebraic expression: $3x^2-4$

$\underset{–}{\text{Need to Find:}}$
Non-constant term and it's coefficient

In the given expression $3x^2-4,$ $\underset{–}{3x^2}$ is the variable term (i.e. non-constant term) as it contains the variable $\underset{–}{x}$, and $-4$ is the constant term as it does not contain any variable.

$\therefore$ The non-constant term is $\underset{–}{3x^2}$ and it's coefficient is $\underset{–}{3}.$

Hence, option (c.) is the correct answer.
