Question
Answer
$$x^2+13x+42+x+7=x^2+14x+49$$
Explanation
| $$ \begin{aligned}x^2+13x+42+x+7& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}x^2+14x+49\end{aligned} $$ | |
| ① | Combine like terms: $$ x^2+ \color{blue}{13x} + \color{red}{42} + \color{blue}{x} + \color{red}{7} = x^2+ \color{blue}{14x} + \color{red}{49} $$ |
