Question
Answer
$$w^2-5w-7-2w+3=w^2-7w-4$$
Explanation
| $$ \begin{aligned}w^2-5w-7-2w+3& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}w^2-7w-4\end{aligned} $$ | |
| ① | Combine like terms: $$ w^2 \color{blue}{-5w} \color{red}{-7} \color{blue}{-2w} + \color{red}{3} = w^2 \color{blue}{-7w} \color{red}{-4} $$ |
