Question
Answer
$$(6m+2)^2=36m^2+24m+4$$
Explanation
| $$ \begin{aligned}(6m+2)^2& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}36m^2+24m+4\end{aligned} $$ | |
| ① | Find $ \left(6m+2\right)^2 $ using formula. $$ (A + B)^2 = \color{blue}{A^2} + 2 \cdot A \cdot B + \color{red}{B^2} $$where $ A = \color{blue}{ 6m } $ and $ B = \color{red}{ 2 }$. $$ \begin{aligned}\left(6m+2\right)^2 = \color{blue}{\left( 6m \right)^2} +2 \cdot 6m \cdot 2 + \color{red}{2^2} = 36m^2+24m+4\end{aligned} $$ |
