| $$ \begin{aligned}-6v(-7v+7)& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-(-42v^2+42v) \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle2}{\textcircled {2}} } }}}42v^2-42v\end{aligned} $$ | |
| ① | Multiply $ \color{blue}{6v} $ by $ \left( -7v+7\right) $ $$ \color{blue}{6v} \cdot \left( -7v+7\right) = -42v^2+42v $$ |
| ② | Remove the parentheses by changing the sign of each term within them. $$ - \left(-42v^2+42v \right) = 42v^2-42v $$ |
