Question
Add $ \, \color{blue}{ 7w^2+4w-6 } \, $ and $ \, \color{orangered}{ w^2-11w+13 }$.
Answer
$$ \left( \color{blue}{7w^2+4w-6} \right) + \left( \color{orangered}{w^2-11w+13} \right) = 8w^2-7w+7 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & 7w^2 & 4w & -6 \\ \color{blue}{ + } & w^2 & -11w & 13 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & 7w^2 & 4w & -6 \\ \color{blue}{ + } & w^2 & -11w & 13 \\ \hline & 8w^2 & -7w & 7 \end{array} $$This page was created using
