Add $ \, \color{blue}{ 4x^2-4x-18 } \, $ and $ \, \color{orangered}{ 4x^2-11x-1 }$.
Answer
$$ \left( \color{blue}{4x^2-4x-18} \right) + \left( \color{orangered}{4x^2-11x-1} \right) = 8x^2-15x-19 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & 4x^2 & -4x & -18 \\ \color{blue}{ + } & 4x^2 & -11x & -1 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & 4x^2 & -4x & -18 \\ \color{blue}{ + } & 4x^2 & -11x & -1 \\ \hline & 8x^2 & -15x & -19 \end{array} $$This page was created using
