Question
Answer
$$4x^2+2-5x^2+6x^8-13x^8=-7x^8-x^2+2$$
Explanation
| $$ \begin{aligned}4x^2+2-5x^2+6x^8-13x^8& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-7x^8-x^2+2\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{4x^2} +2 \color{blue}{-5x^2} + \color{red}{6x^8} \color{red}{-13x^8} = \color{red}{-7x^8} \color{blue}{-x^2} +2 $$ |
