Question
Answer
$$3x^3+8x^4+3x^4-2x^3=11x^4+x^3$$
Explanation
| $$ \begin{aligned}3x^3+8x^4+3x^4-2x^3& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}11x^4+x^3\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{3x^3} + \color{red}{8x^4} + \color{red}{3x^4} \color{blue}{-2x^3} = \color{red}{11x^4} + \color{blue}{x^3} $$ |
