Add $ \, \color{blue}{ 5v^3 } \, $ and $ \, \color{orangered}{ 6v-8 }$.
Answer
$$ \color{blue}{5v^3} + \left( \color{orangered}{6v-8} \right) = 5v^3+6v-8 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & 5v^3 & & \\ \color{blue}{ + } & & 6v & -8 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & 5v^3 & & \\ \color{blue}{ + } & & 6v & -8 \\ \hline & 5v^3 & 6v & -8 \end{array} $$This page was created using
