| ① | Combine like terms: $$ \color{blue}{7m} +11 \color{blue}{-6m} +m^2 = m^2+ \color{blue}{m} +11 $$ |
| ② | Combine like terms: $$ \color{blue}{6} +m^3+ \color{red}{m} \color{green}{-3m^2} + \color{green}{m^2} + \color{red}{m} + \color{blue}{11} = m^3 \color{green}{-2m^2} + \color{red}{2m} + \color{blue}{17} $$ |
