Answer
$$8x^2+3x+5+x^2-2x+1=9x^2+x+6$$
Explanation
| $$ \begin{aligned}8x^2+3x+5+x^2-2x+1& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}9x^2+x+6\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{8x^2} + \color{red}{3x} + \color{green}{5} + \color{blue}{x^2} \color{red}{-2x} + \color{green}{1} = \color{blue}{9x^2} + \color{red}{x} + \color{green}{6} $$ |
