Answer
$$6t^2-5t-1+3t^2-2t+7=9t^2-7t+6$$
Explanation
| $$ \begin{aligned}6t^2-5t-1+3t^2-2t+7& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}9t^2-7t+6\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{6t^2} \color{red}{-5t} \color{green}{-1} + \color{blue}{3t^2} \color{red}{-2t} + \color{green}{7} = \color{blue}{9t^2} \color{red}{-7t} + \color{green}{6} $$ |
