Question
Answer
$$3m-7+2m^2-8m+6=2m^2-5m-1$$
Explanation
| $$ \begin{aligned}3m-7+2m^2-8m+6& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}2m^2-5m-1\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{3m} \color{red}{-7} +2m^2 \color{blue}{-8m} + \color{red}{6} = 2m^2 \color{blue}{-5m} \color{red}{-1} $$ |
