Question
Answer
$$5x^3+3x-5+2x^3+1=7x^3+3x-4$$
Explanation
| $$ \begin{aligned}5x^3+3x-5+2x^3+1& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}7x^3+3x-4\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{5x^3} +3x \color{red}{-5} + \color{blue}{2x^3} + \color{red}{1} = \color{blue}{7x^3} +3x \color{red}{-4} $$ |
