Add $ \, \color{blue}{ 9x^2+6 } \, $ and $ \, \color{orangered}{ 2x^2-x-10 }$.
Answer
$$ \left( \color{blue}{9x^2+6} \right) + \left( \color{orangered}{2x^2-x-10} \right) = 11x^2-x-4 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & 9x^2 & & 6 \\ \color{blue}{ + } & 2x^2 & -x & -10 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & 9x^2 & & 6 \\ \color{blue}{ + } & 2x^2 & -x & -10 \\ \hline & 11x^2 & -x & -4 \end{array} $$This page was created using
