| $$ \begin{aligned}-2(6n+8)& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-(12n+16) \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle2}{\textcircled {2}} } }}}-12n-16\end{aligned} $$ | |
| ① | Multiply $ \color{blue}{2} $ by $ \left( 6n+8\right) $ $$ \color{blue}{2} \cdot \left( 6n+8\right) = 12n+16 $$ |
| ② | Remove the parentheses by changing the sign of each term within them. $$ - \left(12n+16 \right) = -12n-16 $$ |
