Question
Answer
$$6n^3-8n+4n+n^3=7n^3-4n$$
Explanation
| $$ \begin{aligned}6n^3-8n+4n+n^3& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}7n^3-4n\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{6n^3} \color{red}{-8n} + \color{red}{4n} + \color{blue}{n^3} = \color{blue}{7n^3} \color{red}{-4n} $$ |
