Question
Answer
$$3y^2-2y+1+5y^2-y-4=8y^2-3y-3$$
Explanation
| $$ \begin{aligned}3y^2-2y+1+5y^2-y-4& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}8y^2-3y-3\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{3y^2} \color{red}{-2y} + \color{green}{1} + \color{blue}{5y^2} \color{red}{-y} \color{green}{-4} = \color{blue}{8y^2} \color{red}{-3y} \color{green}{-3} $$ |
