Question
Answer
$$5x^2+5-2x^2+3x^3-10=3x^3+3x^2-5$$
Explanation
| $$ \begin{aligned}5x^2+5-2x^2+3x^3-10& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}3x^3+3x^2-5\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{5x^2} + \color{red}{5} \color{blue}{-2x^2} +3x^3 \color{red}{-10} = 3x^3+ \color{blue}{3x^2} \color{red}{-5} $$ |
