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