Add $ \, \color{blue}{ 8s^3+6s^2+3s } \, $ and $ \, \color{orangered}{ 8s^3+6s+2 }$.
Answer
$$ \left( \color{blue}{8s^3+6s^2+3s} \right) + \left( \color{orangered}{8s^3+6s+2} \right) = 16s^3+6s^2+9s+2 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrrr} & 8s^3 & 6s^2 & 3s & \\ \color{blue}{ + } & 8s^3 & & 6s & 2 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrrr} & 8s^3 & 6s^2 & 3s & \\ \color{blue}{ + } & 8s^3 & & 6s & 2 \\ \hline & 16s^3 & 6s^2 & 9s & 2 \end{array} $$This page was created using
