Answer
$$17-3s^2+2s^2-5s^3+5=-5s^3-s^2+22$$
Explanation
| $$ \begin{aligned}17-3s^2+2s^2-5s^3+5& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-5s^3-s^2+22\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{17} \color{red}{-3s^2} + \color{red}{2s^2} -5s^3+ \color{blue}{5} = -5s^3 \color{red}{-s^2} + \color{blue}{22} $$ |
