Add $ \, \color{blue}{ 2x } \, $ and $ \, \color{orangered}{ 3x^2-4x }$.
Answer
$$ \color{blue}{2x} + \left( \color{orangered}{3x^2-4x} \right) = 3x^2-2x $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrr} & & 2x \\ \color{blue}{ + } & 3x^2 & -4x \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrr} & & 2x \\ \color{blue}{ + } & 3x^2 & -4x \\ \hline & 3x^2 & -2x \end{array} $$This page was created using
