Question
Answer
$$8p^2+10p-15+4p^2+12p+3=12p^2+22p-12$$
Explanation
| $$ \begin{aligned}8p^2+10p-15+4p^2+12p+3& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}12p^2+22p-12\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{8p^2} + \color{red}{10p} \color{green}{-15} + \color{blue}{4p^2} + \color{red}{12p} + \color{green}{3} = \color{blue}{12p^2} + \color{red}{22p} \color{green}{-12} $$ |
