Question
Add $ \, \color{blue}{ 7x^2+6x } \, $ and $ \, \color{orangered}{ 8x^2+3x+8 }$.
Answer
$$ \left( \color{blue}{7x^2+6x} \right) + \left( \color{orangered}{8x^2+3x+8} \right) = 15x^2+9x+8 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & 7x^2 & 6x & \\ \color{blue}{ + } & 8x^2 & 3x & 8 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & 7x^2 & 6x & \\ \color{blue}{ + } & 8x^2 & 3x & 8 \\ \hline & 15x^2 & 9x & 8 \end{array} $$This page was created using
