Question
Answer
$$5x^3-2x^2+14x+7x^2+3x-11=5x^3+5x^2+17x-11$$
Explanation
| $$ \begin{aligned}5x^3-2x^2+14x+7x^2+3x-11& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}5x^3+5x^2+17x-11\end{aligned} $$ | |
| ① | Combine like terms: $$ 5x^3 \color{blue}{-2x^2} + \color{red}{14x} + \color{blue}{7x^2} + \color{red}{3x} -11 = 5x^3+ \color{blue}{5x^2} + \color{red}{17x} -11 $$ |
