Add $ \, \color{blue}{ 2x^2+3x-4 } \, $ and $ \, \color{orangered}{ x^2-3x-2 }$.
Answer
$$ \left( \color{blue}{2x^2+3x-4} \right) + \left( \color{orangered}{x^2-3x-2} \right) = 3x^2-6 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & 2x^2 & 3x & -4 \\ \color{blue}{ + } & x^2 & -3x & -2 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & 2x^2 & 3x & -4 \\ \color{blue}{ + } & x^2 & -3x & -2 \\ \hline & 3x^2 & & -6 \end{array} $$This page was created using
