Add $ \, \color{blue}{ 6x^5+1 } \, $ and $ \, \color{orangered}{ 2x^5+9x-1 }$.
Answer
$$ \left( \color{blue}{6x^5+1} \right) + \left( \color{orangered}{2x^5+9x-1} \right) = 8x^5+9x $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & 6x^5 & & 1 \\ \color{blue}{ + } & 2x^5 & 9x & -1 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & 6x^5 & & 1 \\ \color{blue}{ + } & 2x^5 & 9x & -1 \\ \hline & 8x^5 & 9x & \end{array} $$This page was created using
