Add $ \, \color{blue}{ 120 } \, $ and $ \, \color{orangered}{ 2x }$.
Answer
$$ \color{blue}{120} + \color{orangered}{2x} = 2x+120 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrr} & & 120 \\ \color{blue}{ + } & 2x & \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrr} & & 120 \\ \color{blue}{ + } & 2x & \\ \hline & 2x & 120 \end{array} $$This page was created using
