Add $ \, \color{blue}{ x^2-4x-10 } \, $ and $ \, \color{orangered}{ x^2-9x+3 }$.
Answer
$$ \left( \color{blue}{x^2-4x-10} \right) + \left( \color{orangered}{x^2-9x+3} \right) = 2x^2-13x-7 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & x^2 & -4x & -10 \\ \color{blue}{ + } & x^2 & -9x & 3 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & x^2 & -4x & -10 \\ \color{blue}{ + } & x^2 & -9x & 3 \\ \hline & 2x^2 & -13x & -7 \end{array} $$This page was created using
