Add $ \, \color{blue}{ 4a+2 } \, $ and $ \, \color{orangered}{ 6a^2-a+2 }$.
Answer
$$ \left( \color{blue}{4a+2} \right) + \left( \color{orangered}{6a^2-a+2} \right) = 6a^2+3a+4 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & & 4a & 2 \\ \color{blue}{ + } & 6a^2 & -a & 2 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & & 4a & 2 \\ \color{blue}{ + } & 6a^2 & -a & 2 \\ \hline & 6a^2 & 3a & 4 \end{array} $$This page was created using
