Question
Answer
$$-4a^4+16a^4-2a^4-8a+13a=10a^4+5a$$
Explanation
| $$ \begin{aligned}-4a^4+16a^4-2a^4-8a+13a& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}10a^4+5a\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{-4a^4} + \color{red}{16a^4} \color{red}{-2a^4} \color{green}{-8a} + \color{green}{13a} = \color{red}{10a^4} + \color{green}{5a} $$ |
