Question
Answer
$$1-4n^2+5+n^2=-3n^2+6$$
Explanation
| $$ \begin{aligned}1-4n^2+5+n^2& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-3n^2+6\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{1} \color{red}{-4n^2} + \color{blue}{5} + \color{red}{n^2} = \color{red}{-3n^2} + \color{blue}{6} $$ |
