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