Add $ \, \color{blue}{ 9x-5 } \, $ and $ \, \color{orangered}{ 7x^2+9x+2 }$.
Answer
$$ \left( \color{blue}{9x-5} \right) + \left( \color{orangered}{7x^2+9x+2} \right) = 7x^2+18x-3 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & & 9x & -5 \\ \color{blue}{ + } & 7x^2 & 9x & 2 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & & 9x & -5 \\ \color{blue}{ + } & 7x^2 & 9x & 2 \\ \hline & 7x^2 & 18x & -3 \end{array} $$This page was created using
