# How do you simplify and restricted value of (x^2+12x +36)/(9x+18)?

Excluded value $\to x = - 2$
If you factor out you get :$\text{ } \frac{\left(x + 6\right) \left(x + 6\right)}{9 \left(x + 2\right)}$ and I can not spot anything that can be don with this.
The excludes value is $x = - 2$ as this turns the denominator into 0 which is undefined.
