Explanation
| $$ \begin{aligned}4g(-g^2+2)& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-4g^3+8g\end{aligned} $$ | |
| ① | Multiply $ \color{blue}{4g} $ by $ \left( -g^2+2\right) $ $$ \color{blue}{4g} \cdot \left( -g^2+2\right) = -4g^3+8g $$ |
