| $$ \begin{aligned}(-3+4)(-2m-4)& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}1(-2m-4) \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle2}{\textcircled {2}} } }}}-2m-4\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{-3} + \color{blue}{4} = \color{blue}{1} $$ |
| ② | Multiply $ \color{blue}{1} $ by $ \left( -2m-4\right) $ $$ \color{blue}{1} \cdot \left( -2m-4\right) = -2m-4 $$ |
