Answer
$$2x^2-6x-5-9x^2+5x-4=-7x^2-x-9$$
Explanation
| $$ \begin{aligned}2x^2-6x-5-9x^2+5x-4& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-7x^2-x-9\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{2x^2} \color{red}{-6x} \color{green}{-5} \color{blue}{-9x^2} + \color{red}{5x} \color{green}{-4} = \color{blue}{-7x^2} \color{red}{-x} \color{green}{-9} $$ |
