| $$ \begin{aligned}4t\cdot(3-t)& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}12t-4t^2 \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle2}{\textcircled {2}} } }}}-4t^2+12t\end{aligned} $$ | |
| ① | Multiply $ \color{blue}{4t} $ by $ \left( 3-t\right) $ $$ \color{blue}{4t} \cdot \left( 3-t\right) = 12t-4t^2 $$ |
| ② | Combine like terms: $$ -4t^2+12t = -4t^2+12t $$ |
