Question
Add $ \, \color{blue}{ 5x+3 } \, $ and $ \, \color{orangered}{ -19x+2 }$.
Answer
$$ \left( \color{blue}{5x+3} \right) + \left( \color{orangered}{-19x+2} \right) = -14x+5 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrr} & 5x & 3 \\ \color{blue}{ + } & -19x & 2 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrr} & 5x & 3 \\ \color{blue}{ + } & -19x & 2 \\ \hline & -14x & 5 \end{array} $$This page was created using
