Add $ \, \color{blue}{ x-7 } \, $ and $ \, \color{orangered}{ x^2-x-3 }$.
Answer
$$ \left( \color{blue}{x-7} \right) + \left( \color{orangered}{x^2-x-3} \right) = x^2-10 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & & x & -7 \\ \color{blue}{ + } & x^2 & -x & -3 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & & x & -7 \\ \color{blue}{ + } & x^2 & -x & -3 \\ \hline & x^2 & & -10 \end{array} $$This page was created using
