$$-6m^2n^2+3mn+4mn+13m^2n^2+9=7m^2n^2+7mn+9$$
Explanation
| $$ \begin{aligned}-6m^2n^2+3mn+4mn+13m^2n^2+9& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}7m^2n^2+7mn+9\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{-6m^2n^2} + \color{red}{3mn} + \color{red}{4mn} + \color{blue}{13m^2n^2} +9 = \color{blue}{7m^2n^2} + \color{red}{7mn} +9 $$ |
