Explanation
| $$ \begin{aligned}5x-8x^4+6x+x^4& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-7x^4+11x\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{5x} \color{red}{-8x^4} + \color{blue}{6x} + \color{red}{x^4} = \color{red}{-7x^4} + \color{blue}{11x} $$ |
