Question
Answer
$$3x^2-x+1+15-9x-2x^2=x^2-10x+16$$
Explanation
| $$ \begin{aligned}3x^2-x+1+15-9x-2x^2& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}x^2-10x+16\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{3x^2} \color{red}{-x} + \color{green}{1} + \color{green}{15} \color{red}{-9x} \color{blue}{-2x^2} = \color{blue}{x^2} \color{red}{-10x} + \color{green}{16} $$ |
