Question
Answer
$$2x^3+4x-6+2x^3+1=4x^3+4x-5$$
Explanation
| $$ \begin{aligned}2x^3+4x-6+2x^3+1& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}4x^3+4x-5\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{2x^3} +4x \color{red}{-6} + \color{blue}{2x^3} + \color{red}{1} = \color{blue}{4x^3} +4x \color{red}{-5} $$ |
