\(|2x+5|-6^2=-14-9\)
\(\Rightarrow|2x+5|-36=-23\)
\(\Rightarrow|2x+5|=-23+36\)
\(\Rightarrow|2x+5|=13\)
\(\Rightarrow\orbr{\begin{cases}2x+5=13\\2x+5=-13\end{cases}}\)
\(\Rightarrow\orbr{\begin{cases}2x=13-5\\2x=-13-5\end{cases}}\)
\(\Rightarrow\orbr{\begin{cases}2x=8\\2x=-18\end{cases}}\)
\(\Rightarrow\orbr{\begin{cases}x=8\div2\\x=\left(-18\right)\div2\end{cases}}\)
\(\Rightarrow\orbr{\begin{cases}x=4\\x=-9\end{cases}}\)
Vậy x = 4 hoặc x = -9.
