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