Add $ \, \color{blue}{ -7x^2+3x-10 } \, $ and $ \, \color{orangered}{ -6x^2-10x+3 }$.
Answer
$$ \left( \color{blue}{-7x^2+3x-10} \right) + \left( \color{orangered}{-6x^2-10x+3} \right) = -13x^2-7x-7 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & -7x^2 & 3x & -10 \\ \color{blue}{ + } & -6x^2 & -10x & 3 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & -7x^2 & 3x & -10 \\ \color{blue}{ + } & -6x^2 & -10x & 3 \\ \hline & -13x^2 & -7x & -7 \end{array} $$This page was created using
