| $$ \begin{aligned}x^2+9x+8x^2+3x-40& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}9x^2+12x-40\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{x^2} + \color{red}{9x} + \color{blue}{8x^2} + \color{red}{3x} -40 = \color{blue}{9x^2} + \color{red}{12x} -40 $$ |
