Add $ \, \color{blue}{ 8x^2 } \, $ and $ \, \color{orangered}{ 4x }$.
Answer
$$ \color{blue}{8x^2} + \color{orangered}{4x} = 8x^2+4x $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrr} & 8x^2 & \\ \color{blue}{ + } & & 4x \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrr} & 8x^2 & \\ \color{blue}{ + } & & 4x \\ \hline & 8x^2 & 4x \end{array} $$This page was created using
