Question
Add $ \, \color{blue}{ 6c^2-2c-1 } \, $ and $ \, \color{orangered}{ -4c^2+7c+5 }$.
Answer
$$ \left( \color{blue}{6c^2-2c-1} \right) + \left( \color{orangered}{-4c^2+7c+5} \right) = 2c^2+5c+4 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & 6c^2 & -2c & -1 \\ \color{blue}{ + } & -4c^2 & 7c & 5 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & 6c^2 & -2c & -1 \\ \color{blue}{ + } & -4c^2 & 7c & 5 \\ \hline & 2c^2 & 5c & 4 \end{array} $$This page was created using
