Explanation
| $$ \begin{aligned}-7^4+20x+3x^4-2x& \xlongequal{ }-2401+20x+3x^4-2x \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}3x^4+18x-2401\end{aligned} $$ | |
| ① | Combine like terms: $$ -2401+ \color{blue}{20x} +3x^4 \color{blue}{-2x} = 3x^4+ \color{blue}{18x} -2401 $$ |
