Question
Answer
$$x^3+4x+5x^3+8x-11=6x^3+12x-11$$
Explanation
| $$ \begin{aligned}x^3+4x+5x^3+8x-11& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}6x^3+12x-11\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{x^3} + \color{red}{4x} + \color{blue}{5x^3} + \color{red}{8x} -11 = \color{blue}{6x^3} + \color{red}{12x} -11 $$ |
