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