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