Add $ \, \color{blue}{ 6x^2+3x-3 } \, $ and $ \, \color{orangered}{ 2x-2 }$.
Answer
$$ \left( \color{blue}{6x^2+3x-3} \right) + \left( \color{orangered}{2x-2} \right) = 6x^2+5x-5 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & 6x^2 & 3x & -3 \\ \color{blue}{ + } & & 2x & -2 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & 6x^2 & 3x & -3 \\ \color{blue}{ + } & & 2x & -2 \\ \hline & 6x^2 & 5x & -5 \end{array} $$This page was created using
