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