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