Answer
$$7m^4+6m^2+7+2m^4-3m^2+1=9m^4+3m^2+8$$
Explanation
| $$ \begin{aligned}7m^4+6m^2+7+2m^4-3m^2+1& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}9m^4+3m^2+8\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{7m^4} + \color{red}{6m^2} + \color{green}{7} + \color{blue}{2m^4} \color{red}{-3m^2} + \color{green}{1} = \color{blue}{9m^4} + \color{red}{3m^2} + \color{green}{8} $$ |
