Question
Add $ \, \color{blue}{ 16r^2-2r } \, $ and $ \, \color{orangered}{ 4r^2+6r }$.
Answer
$$ \left( \color{blue}{16r^2-2r} \right) + \left( \color{orangered}{4r^2+6r} \right) = 20r^2+4r $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrr} & 16r^2 & -2r \\ \color{blue}{ + } & 4r^2 & 6r \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrr} & 16r^2 & -2r \\ \color{blue}{ + } & 4r^2 & 6r \\ \hline & 20r^2 & 4r \end{array} $$This page was created using
