Add $ \, \color{blue}{ x^2+5x+6 } \, $ and $ \, \color{orangered}{ x+2 }$.
Answer
$$ \left( \color{blue}{x^2+5x+6} \right) + \left( \color{orangered}{x+2} \right) = x^2+6x+8 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & x^2 & 5x & 6 \\ \color{blue}{ + } & & x & 2 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & x^2 & 5x & 6 \\ \color{blue}{ + } & & x & 2 \\ \hline & x^2 & 6x & 8 \end{array} $$This page was created using
