Best ResponseYou've already chosen the best response.1we can rewrite that inequality as below: \[\left( {3x  4} \right)\left( {3x + 4} \right) > 0\] so the starting inequality is equivalent to the subsequent two systems of inequalities: \[\left\{ \begin{gathered} 3x  4 > 0 \hfill \\ 3x + 4 > 0 \hfill \\ \end{gathered} \right.,\quad \left\{ {\begin{array}{*{20}{c}} {3x  4 < 0} \\ {3x + 4 < 0} \end{array}} \right.\] please solve them

Best ResponseYou've already chosen the best response.2you could have also have found the turning points and their nature and drawn a rough graph which might have looked like dw:1444420588420:dw
