Explanation
| $$ \begin{aligned}8.54x+11.67x^2-11.49-11.93x^2-24.42& \xlongequal{ }8x+11x^2-11.49-11x^2-24.42 \xlongequal{ } \\[1 em] & \xlongequal{ }8x+ \cancel{11x^2}-11 -\cancel{11x^2}-24 \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}8x-35\end{aligned} $$ | |
| ① | Combine like terms: $$ 8x+ \, \color{blue}{ \cancel{11x^2}} \, \color{green}{-11} \, \color{blue}{ -\cancel{11x^2}} \, \color{green}{-24} = 8x \color{green}{-35} $$ |
