Write the coefficient of $x^2$ in each of the following:$ 9-12 x+x^{3} $<

Given :

The given expression is \( 9-12 x+x^{3} \).

To do :

We have to find the coefficient of $x^2$ in the given expression.

Solution :

Coefficient :

A coefficient is the numerical part of a product of numbers and variables.

\( 9-12 x+x^{3}=x^3+0 x^2-12x+9 \)

Here, $x^2$ is multiplied by $0$.

Therefore, the coefficient of $x^2$ in the given expression is $0$.
