According to the question, the given rational expression can be simplified which is as shown below:

Rational expression = \frac{12-4x}{x^{2} -9}=\frac{4(3-x)}{(x-3)(x+3)}

For the simplification of the given expression, calculate the factors of the numerator as well as denominator terms and divide them from each other. In this change the sign of the expression before dividing with each other.

Rational expression = \frac{-4}{(x+3)}

The rational expression are also known as polynomial expression. The highest degree of these expression is two. And these expression uses concept of factor rule.

Therefore, the final expression is \frac{-4}{(x+3)}

What is polynomial expression?

Polynomial expression are those equation whose highest degree is two. It is also called as quadratic equation. And it is simplified by performing the factors on the given expressions.
