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