Explanation
| $$ \begin{aligned}-4a+6b-2a^2-3a+b& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-2a^2-7a+7b\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{-4a} + \color{red}{6b} -2a^2 \color{blue}{-3a} + \color{red}{b} = -2a^2 \color{blue}{-7a} + \color{red}{7b} $$ |
