Question
Answer
$$t^2-4t-7-6t+5=t^2-10t-2$$
Explanation
| $$ \begin{aligned}t^2-4t-7-6t+5& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}t^2-10t-2\end{aligned} $$ | |
| ① | Combine like terms: $$ t^2 \color{blue}{-4t} \color{red}{-7} \color{blue}{-6t} + \color{red}{5} = t^2 \color{blue}{-10t} \color{red}{-2} $$ |
