Question
Answer
$$8n-2n^2+4n-8n^2=-10n^2+12n$$
Explanation
| $$ \begin{aligned}8n-2n^2+4n-8n^2& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-10n^2+12n\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{8n} \color{red}{-2n^2} + \color{blue}{4n} \color{red}{-8n^2} = \color{red}{-10n^2} + \color{blue}{12n} $$ |
