Question 1090339
The critical x values are  {{{2/3}}} and {{{-4}}}.
{{{2/3}}} is a root of the left-side, and {{{-4}}} is the x-value for which the inequality is undefined.


Test the inequality in each of the three intervals,  {{{x<-4}}}, {{{-4<x<=2/3}}}, {{{x>=2/3}}}.  Which intervals make the inequality true?  Those are the solutions.
