Question
Answer
$$n^2+2n-24n^2-11n+28=-23n^2-9n+28$$
Explanation
| $$ \begin{aligned}n^2+2n-24n^2-11n+28& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-23n^2-9n+28\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{n^2} + \color{red}{2n} \color{blue}{-24n^2} \color{red}{-11n} +28 = \color{blue}{-23n^2} \color{red}{-9n} +28 $$ |
