Explanation
| $$ \begin{aligned}3-3n^4-4-6n^4& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-9n^4-1\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{3} \color{red}{-3n^4} \color{blue}{-4} \color{red}{-6n^4} = \color{red}{-9n^4} \color{blue}{-1} $$ |
