Add $ \, \color{blue}{ 4x } \, $ and $ \, \color{orangered}{ 2x+5 }$.
Answer
$$ \color{blue}{4x} + \left( \color{orangered}{2x+5} \right) = 6x+5 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrr} & 4x & \\ \color{blue}{ + } & 2x & 5 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrr} & 4x & \\ \color{blue}{ + } & 2x & 5 \\ \hline & 6x & 5 \end{array} $$This page was created using
